Thanks, but I meant it to be clearly a rhetorical question.
I already knew what my pinion angle was, and didn't want it changed, just the perches moved from stock B-body, to A-body with 3" spring relocation.
No experienced fab/weld shop would relocate the perches only based on the above info, and additionally, they would want it (angle in degrees and perch ctr to ctr dim and if any offset is desired) in writing, to eliminate potential call backs. The members previous reply on tack welding is the tried and true method.
Seems like the story is still missing some details, and since I'm newly on the OP's Ignore list, I don't have any issue with "pulling the curtain back".
So nobody quote me here.
