brady, what you've got there is pretty much exactly what I plan to build! Do you have any more pics or a build thread here? I'd love to learn more about what you did and what parts you used. Looks like you used a lower arch rear spring, too.

Default Re: Tommy R Attempts to Build a Hot Rod Model A

I've got a stupid question, but that's never stopped me from asking them before.

I'm trying to determine my rear spring, perch, and crossmember setup. I was planning on using my '40 front spring with a flat crossmember since Bass used a similar setup on his coupe ('39 front spring). But he recently told me that it was too soft and he had to add several leafs to it. He recommended a '37-'41 rear spring instead. I guess that's what I'll look for unless someone can convince me why I should continue with my original plan with the '40 front spring?

Also, I'm curious about how to set the rear ride height. It seems there are several variables here.
- crossmember height
- spring rate/arch/etc.
- spring perch design on the axle

And of course, none of this factors in the weight that will eventually be weighing the car down. So what's the best way to determine where to weld the crossmember? Just burn it in and hope for the best??

I plan to use a '40 front spring on the rear of my coupe. My build is similar to your's and brady1929's. The I've got a 2" round tube crossmember with a spring mount in back and plan to add shock mounts something like the So-Cal rear crossmember. If I was doin' it again, I would get the So-Cal crossmember. The rear spring perches are Pete and Jakes and will be spaced 42 1/2" apart. That's only 4" inside the back edge of the 9" Bronco backing plates but is still 1 1/4" outside the frame rail on each side.
Talkin' about the '40 front spring. Rusty used a '40 front on Bubbaluv's coupe, and Bass ended up changin' it to lower the ride height but he didn't say how.
I'm still measurin' and haven't started to weld yet, but you are welcome to check out the "kid's coupe" Albums on my profile page.

Thanks, brady! That's all very helpful information! I forgot if I asked you, but do you have a build thread for your car? Would love to check it out if you do...

Are you talking about item "C" in this pic from the So-Cal site? Looks decent and the price isn't too bad...


See, this is what's confusing to me about what rear spring to use.... Brian (Bass) told me his '39 front spring was too soft in the rear so he had to add several leafs to it. But apparently, the '40 front would be too stiff since the ride height was too high on Bubbaluv's chassis. I didn't think there was that much of a difference in these springs, but I've been wrong a few billion times before.

I know that there are Posie's springs out there that'll work for me, but they're awfully pricey and I'm on a pretty tight budget. Meanwhile, I've got feelers out for a '37-'41 Ford rear spring, per Bass' recommendation. But I'm re-reading the Bubbaluv thread to see if I can find how Bass was going to make that '40 front spring work out.

Thanks! 4" chop is the plan. I think it'll be enough for the right attitude while still giving me (6'1") enough interior room.

My pleasure. Thanks for watching! But I think you lost me on the Jr comment?

By the way, I found out what Bass did to get the Bubbaluv coupe's altitude adjusted...

Thanks...it's a different spring from my parts stash. I'm not really sure what it's out of, but I suspect it may be a '35-36 front spring.
Not much help, unfortunately, since Brian wasn't sure what the spring came from.

Yes... item "C"... You could always look for something on the auction site, use a 2" square tube like brady1929, or fab your own... I'm going to use my '40 front spring on the rear. I was originally going to use a '40 rear spring, but the perch dim is 48" and that puts the spring mounts awfully close to the bearing housings on that early Bronco axle. If the front spring doesn't work out, then I'll do something else... Too many people running front springs on the rear, even Bass... Just take out leaves if too many, add leaves if not enough...

Have you seen this thread???

Yeah, the width of the '40 rear spring concerns me, too....especially 'cause I may want to put some wider wheels/slicks on it from time to time. And thanks for the link as I hadn't seen it and it had some good info!

I'm thinking my best bet now may be to either try my '40 front spring or pony up the bucks for a Posie (AJ40NH). I'd like to try the '40 spring and if it doesn't work, buy the Posie's. The problem is the '40 front spring has 42.5" perches and the Posie's is 44". So I would have to relocate the perches if I swapped down the road.

Crap. Maybe I should just get the damn Posie's spring and pay for the peace of mind!

have you tried a local spring shop. inland trucking i think is pretty much a nation wide company and can pop one out to spec.

That might work if I knew what the hell I needed like material thickness, arch, eye to eye distance, etc...

Start with the '40. If it doesn't work out, have Inland built a couple leafs for it to beef it up, or soften it out. They should be able to work with a stock spring pack and replace a couple of the leaves with thicker/thinner pieces.

Thanks, Jason. And timely, too, as I was just about to post here....

I got a reply from Rusty and he said that the '40 front should work fine, but I could always add some leafs to it, if need be. Jason, I'll take yours and cadillac coffin's idea and just hit up a local spring shop if the '40 front spring is too soft. This'll also save me a few bucks....at least in the short term.

On another note, I got my buddy's plasma torch working last night and lopped off the perches and shock mounts from the rear axle. I'll grind it smooth this week and another friend just offered to let me use his soda blaster whenever I want. That'll come in handy big time! Oh, and I'm finally picking up an oxy/acetylene rig this week. It's just a peanut rig, but I think it'll be enough for me since I likely won't use it that often.

Got the frame table leveled this week and also built a dolly for the body to make it easier to move around. It may not sound like much and there certainly isn't much to share pics of, but progress is happening....sloooooowly, but surely!
