I'm looking for your suggestions for spring hangers to mount an A rear spring to an 8" ford. This will be in an A frame, y-block, T-5. I'm using a '46 front axle and spit bones and would like to use similar rear bones for the consistant look. Also, if any has the spacing dimensions from hanger to hanger for the stock model A width. Thanks for your help. RB
44 if using 36 ford rear radius rods with stock spring and crossmember ,Shackles are 2 and 1/2 So 44 -5 = 39 The width of a model A spring .Only problem with radius rods is getting exhaust on either side of rods ....... I tucked mine up to tight ......
Stock Model A rear spring perches are spaced 49-1/2" apart, eye to eye. Are you planning to mount the spring above the rearend (stock Model A style) or behind it as on later models?
Thanks for the info. It's a '29 sport coupe on an "A" frame, so will "spring over axle" to keep the axle in the right place. RB
That's correct. Don't recall offhand what the spacing is between the leaf holes when the spring is loose - something like 42" rings a bell. With the shackles in place the spring still needs to be spread quite a bit to mount it, and they pack quite a wallup.
Your telling me. I built a spring spreader this weekend. There sure is a lot of tension in a new spring...
I know this posting is old, but I need this info today. I found at Posies page that the hangers holes are 48.5" width. What is the right width 49.5 or 48.5? I use a 1951 F1 rearend in a A V8 rpu, with the hangers in front of the axle. I dont`t want to weld it in the wrong place. Thanks for any info.
POSIES Offers 3 widths (lengths) for Rear Model A springs. These are based on perch eye (hanger) dimensions: 29-31R - Perch eyes 48 - 49 1/2" (will work on stock Model A rear axles) 29-31R-C - Perch eyes 46 - 46 1/2" (narrow) 29-31R-N - Perch eyes 44 - 44 1/2" NEW ITEM DUE Mid October (ultra narrow) I'll post a link later today concerning load vs arch vs spring eye to eye distance. Thanks Todd @ POSIES SuperSlide Springs

I know this is an old thread. I'm working on setting up the frame. Do I want to set up the front axle or rear axle first? For the front, I'm going with a 4 link instead of hairpin. I'm wanting to use a 8.8 rear. I have one rear housing that I dt think will work cause it's too short. The other one, I'm wondering if I can run full fenders or not. Any suggestions?
Just curious, why an 8.8? The one in my F150 is eating axles since there is no inner bearing race and the bearings run directly on the axles.
