    are '49-'54 lower arms interchangable? Want to find another set to do this to rather than cutting up the ones currently on my '54...

    I think its 49-52. 53 and 54 used different uprights, but they interchange with 49-52. the later uprights give you an additional 1/2 to 3/4 inch of drop. You might check around cause I think the uprights are the only difference, but Im not positive.

    I did it, think it should work out ok. I put a plate on the controll arm 1st before putting the link back on. I countersunk it into the arm so that the diamention stay the same. I haven't put the springs back in yet or put it on the ground but it looks like I will end up with 4 to 5"s between the controll arm and the pavement. Need to get the steering arms set up now for the rack.

    Got the bearing adptor and caliper mount from Street Rod Headquarters.
    Not real happy with it though, none of the holes lined up and the bearing adptor didn't work real good eather.Had to do alot of work to get any of it to fit. Rotors/calipers/pads from NAPA.

    Got the springs back in and the steering rack in. To my surprize the 2" drop steering arms didn't work but I put the stock ones back on and they are perfect. So I have a set of dropped arms for sale now.

    Yeah, no need for dropped arms with this mod. I'm glad this thread still pops up now and then and that it has helped so many with their projects!

    Dropped my 54 this past couple weekends using this thread. The rear is 3" blocks, and the front is stepped lower arms, and 1 1/4 coils cut. My coils must have sagged a lot over the last 60 years. Now my front is a little to low. It's fine sitting but once a driver gets in the exhaust is on the ground. So hunting for some new coils. This time only cutting a half coil if any at all. Either way it looks bitchin! LOL

    I wish but it's still to low. Once we pack the wife and kids with me the cross member is almost on the ground. I do love the stance!

    Anybody ever considered doing this for a monetary fee for those who don't weld? For instance, say a guy has a '54 chevy 150 and wants it lowered. The guy has never welded a day in his life but wants his car lowered just a bit. Now, instead of spending a bunch of cash on a welder and a year to learn (the guy is buying a welder but not for a while, and it'll be even longer till his skills are good enough for this type of thing) he could ship the arms to someone who has done it successfully, have them do it and ship them back.

    There's no more liability in it than any other suspension modification(bag job, front clip swap/mustang II install, four link install, etc). I've done several sets of control arms for other people.

    I like this technique a lot and plan to do it on the '50 I'm picking up. One thing tht I need help understanding is why this won't affect the geometry and bump steer? I'm unable to visualize. Someone please explain this.

    It does affect the geometry, but not enough to cause bumpsteer. After we did this to my brother's 52 it actually improved the feel of the steering.

    Steering is much more nimble now. Also feels lighter. I love the way the car handles now.
