I picked up a ‘32 that has a semi-traditional “lakes look” roadster with ‘39 underpinning. My problem is that the frame has been C-notched and lightly notched/ boxed for the radius arms (closed drive shaft, banjo rear)..but she’s hitting on the radius arms over any small bump..I’d really like to keep my stance as it is if at all possible. I can find a lot on C-notching the frame but not much on clearance for the radius rods? I’ve seen a few things were guys start the notching before the rods and sweep up to what would be the C-notch depth and sweep back out to the rear crossmember. It’s been boxed and it looks good..but seems to be a lot of structure to remove even though it’s no deeper than the initial C-notch? I guess my other options are, box the notch deeper, more like the C-notch or go inboard with the split ‘35-‘36 bones which opens up another can of worms. I’d love any idea of advice you could give... I hope I didn’t miss information that’s already been posted. Sent from my iPad using The H.A.M.B. mobile app
Make up a bracket to weld onto the axle tubes and move the radius rods inboard, adjusting them to suit the forward mount. Or there's a set-up sold on here that does that with the addition of F1 shock mounts, never used them, don't know the guy but they look like a good idea. Here's a link. https://www.jalopyjournal.com/forum...r-shock-wishbone-mount.1119383/#post-12708051
common issue. what you have sounds like it just needs to be relieved a little more. here are a few examples: Nealinca modified the tubes to avoid relieving the frame. https://www.jalopyjournal.com/forum/threads/tech-a-10-32-wishbone.519077/page-3 here is a rolling bones chassis relieved. https://www.jalopyjournal.com/forum/threads/the-cain-32-roadster-build.497401/
I had this same issue on my build. C notched frame, 37 rear and bones, even shortened bones about 6”. I took three leaves out of 40 Ford rear spring during build. First weekend drive noticed the bones hitting on rough spots in road. I put the leaves back and problem went away. I know you said you didn’t want to change the stance, but it is the easiest way.
