so my rack says: SPR GM 56H06B i cant find what it is,my problem is i need a universal joint to fit the input splines and so far the 5/8 36 spline joint does not fit.im at a standstill with this
no other number i see on it. and nothign pops up on the net when i search those numbers.iy measures 5/8 but my 5/8 coupler is to small.it has 36 splines but it has a factory flat spot on the splines.very confused what to get. as from what i can tell theres a ford racl,a chevy and chrysler and the chevy/chrysler have the same spline and measurement. so i am unsure what universal joint i need.
I have the same problem with a rebuilt manual rack off a early 90's cavalier. After all the description i gave boregeson they sent me for a power rack which is different. So i'm running a power rack like a manual till i find the splined unit.
that would be the biggest help,im lost and am stuck on my progress till i can get that figured out and hooked up
thanks for searching.maybe another will chime in.i contacted borgeson and the offered little to no help
You might have to go to a late model wrecking yard and pull a u joint of an ninty's type gm frd and see if it fits perhaps as a sample or adapt some how to use. Any thing newer then 1985 is probably metric.
Could be 17DD rather than 3/4DD. My C4 R&P is metric. not imperial. Borgeson has the joint as I have one to suit 3/4DD & 17DD.
16 mm is real close to 5/8. That may be what you have. HF has a digital dial caliper around $20, sometimes on sale for much less that reads both metric & standard, get one, you'll wonder how you got by w/o it.
Not to hijack the thread but he might be looking for the same thing i am. I specified to borgeson what i had and they said ya ya ya. But sent me one for a power rack anyway. So, i'm reluctant to order from them again.
This is really starting to bother me. I pulled this off several years ago. I keep exceptional records, most of which I can quote from memory. I had the joint. Now I can't find the records, and a bunch of pictures (not related), from that period of time. Paperless office, they said. One bit-shift, and it is all lost. Technological failure I can accept. My memory, on the other hand, is beginning to worry me.
