I just got perches from Mancini. I need to know if you set the perches on same plane as the machined pad for snubber, or if there is a slight angle to them that needs to be duplicated. Even though I don't get thru this place that often, I still lurk a little and really appreciate all of you folks and the knowledge you share! Thanks in advance for your help!

You might get the car setup & weld em at the particular angle you need to get YOUR vehicle ujoints parallel but in different planes but wait & see what the Doc has to say. I'm in the same situation & am wondering if I should get the leafs as level as I can then set the housing on top of em then tack em so they are parrallel/correct angle or get the pads equal on the bench. live every 24 hour block of time like it's your last day on earth

I had the rearend in the car with desired angle before welding. Might as well get it exact.

I had the rearend in the car with desired angle before welding. Might as well get it exact. Sorry, forgot I also used the good Dr's 1 inch relocation brackets. That's the reason for 44" compared to the stock 46". Bottom line, as stated, set-up in car before welding. Then you can also correct the side-to-side offset these cars always seem to have. Stock rears are never centered on the body, leaving a bigger gap on 1 side and rub on the other when you try to stuff bigger tires in.
