Just a question regarding my 32 Ford rear suspension, Its a 9" diff with split wishbones (about 10" apart) using threaded in rubber bush type joints up front (not heim joints) , at the back of the wishbone appears to be an original style forged perch attached to the wishbone. The diff housing has a flat steel piece welded to it that wraps 1/2 way around the diff almost and has 2 mounting holes drilled in it. The perch has a slot or recess in it that the flat steel fits into and is bolted through with two 1/2" bolts. Because the perch is forged it doesnt squeeze in tight onto the diff mounting steel piece, so there is some movement where the perches attach to the diff. At first I was thinking of drilling out one side of the perch and using a cap screw so the head was supported by one side of the perch and the other side is bolted up tightly to the diff mount. But then i had second thoughts about creating a bind because the wishbone is split, and I had also noticed that when my rear buggy spring was removed the suspension had no bind and would rock easily side to side when supported in the centre (because the looseness of the perch attachments) My question is what is the normal way of attaching split wishbone perches to the diff, is there normally any movement left in the mounts or is it to be tightened up tight ?
