    Maybe this has been covered before and I jus couldn't find it but, can a '39 Ford transmission bolt up to a stock model A Ford without, or limited modification?

    No it won't. You have to run a adapter Clings aftermarket products carries them. Have one on my model a.

  3. The kits sold for this conversion also include a bracket to mount the pedals and wishbone. The contact for Clings is clingsaftermarket.com, (480) 777-1202 A direct link to what you looking for: http://clingsaftermarket.com/addtocart.asp?prod=3000 You still need to mount your master cylinder if you are running hydraulic brakes. I would suggest looking into the heavy duty battery box that incorporates a master cylinder mount. It would be good to post on fordbarn asking who makes the best kits.

    For the time and money involved making the change I would just put up with the Model A transmission.

  4. V8 trans, weather it is a '39 or earlier on a Model A it a wonderful thing. I have three of them now all using the Clings kit. I also have a partial kit to mount V8 trans along with a V8 engine in one Model A. It's nice to have syncros on the top two gears but the big deal is the split between ratios. More even on the V8 trans as opposed to the A trans. Clings also makes a setup to mount a master cylinder if you go with "juice" brakes.

    A little tip on the conversion kits: You also need a V-8 universal joint housing (held together with 4 bolts, whereas the A housing has 6 bolts). This does not come with the kit. So if you don't already have one attached to the back of the '39 trans you intend to use, get one before you tear everything apart. Ask me how I learned this...:oops:

    Ok ,so you need the V8 universal joint housing etc. Now if the A motor is mounted at front and rear , do you still need the float a motor mount at the universal joint , as the model A float a motor mount wont fit the V8 universal joint cup ??

    Hey @Kiwi 4d - The Model A float-a-motor rear trans mount will NOT fit the V-8 universal joint housing. I tried like crazy to find one that fits (I know they exist because a buddy has one), but it appears they are not made anymore. I wound up making my own, as seen here (float-a-motor on right and my crude but effective version on the left). trans-brackets.jpg
    Here it is installed, although you really can't see much:
    trans-bracket installed.jpg
    It's not really a mount. More of a support/stop to keep the trans from dipping down. I'm not an expert, but I think it's primary purpose is to prevent clutch chatter.

    That's pretty slick, but I intend to keep the original solid mounts...for now.

    I should start looking then, what did they come on originally? Thank for the tip.

    I think they're the same, 1932-1948. Lots of them on eBay, used and inexpensive repop.
     
  12. Is it less work to put in a “B” trans stuffed with later gears? I know you still have to figure out pedals and modify the pan.

    But will the B trans work with a flathead later on?

  14. No. I guess it won’t. I missed that part of the plan! Sorry!
     
  15. The gears and shifter will work but the case is different between a B and a V8.

    Assuming so, which is why I'd run the '39 with the Clings adapter until upgrading to a flathead...if I ever do.

  17. received_10212443796558604.jpeg Running a clings adapter with a 35 trans. Both purchased from hamb/ford barn. The Clings kit didn't come with instructions so I missed the part about drilling through the bottom of the bellhousing for the wishbone bracket. Out with the rear end and trans!

  18. I have a '38 V8 trans with late '39 gears in my '29, what an improvement! As mentioned, easier shifting and better gear ratio's. The Cling's adapter made it a easy upgrade.

    Burnzy37 and 1stGrumpy, that's looks like what I'm looking for. All good information. Really nice looking setup Burnzy37, nice motor and intake!

  20. You'll need a B flywheel housing too and you'll need to make your own side mounts as no one makes them anymore. Also don't forget the wishbone mount

    Tiny, which is why, to me, the Cling's setup makes more sense.
     
  22. I'm not going to argue with you on that.

    Unless you have access to all of the B parts and have the time to put it together. Not only do you need the B flywheel housing, but the lower housing too; which is part of the B oil pan. The B pan won't work on the Model A engine without modification. So if you have the money for the adapter, that is the fastest,easiest way to go.
     
  24. Any pics of the wishbone mount with radius ball and cups attached? Still trying to figure that part out! Are you using original caps and rubber ball?
    Thanks, burnzy
     

  25. burnzy...
    Sorry, I never thought to get any pictures of the wishbone attached. Here's the link to Clings, good people and very helpful, www.clingsaftermaket.com
    The mount is a simple install, mounts to 2 of the lower adapter bolts and a hole needs to be drilled in the bottom of the bellhousing. I used the original style caps but not the rubber ball.
    Grumpy..
     
  26. I forgot about the lower half. I think it would be a neat way to go. Probably the way it was done "back in the day" before adapters. I've collected everything to do it this way but as many have said the Clings adapter is way easier

    They were making these conversion kits long before Clings. Mine is an old Ansen setup:
    Ansen adaptor.jpg
    If you read the history on the Clings site, he says he was inspired to create his kit years ago after buying an exisiting kit and discovering how poorly engineered it was. I don't know what brand he was comparing, but I'm here to tell you he was right. My adaptor itself is the cat's pajamas, all polished up with the nice Ansen Automotive lettering. But I had to grind nearly half an inch of meat out of the inside to make room for the starter. And the replacement support for the pedals is way too frail. Even after I added a stiffener, it still deflects half an inch each time I depress the clutch. And there's no back-stop provision on it for the brake pedal--I crafted a stop on the floor.

    I just bought a Clings pedal support bracket (they also sell their kit parts separately). It's a very well-made piece and is going into my car this winter.

  28. The kit I bought off the hamb contained the original adapter but all the bracket pieces are homemade by the looks.
    My original top cap won't fit in the gap of the wishbone bracket so I'm assuming they both attach underneath?
    Have spoken with Dennis cling a couple of times, he's been a great help.
     
  29. Got a picture?
