Newbie here, hello to all!
I'm putting  a cobra irs in a 47 ford pickup for a customer. Having trouble finding what angle the lower a-arm is on a stock cobra. In all the phots I have seen, the lower arm is tillted up on the front pivot.
I believe this angle to be critical. If anyone chould help, it would be great. I could also used the vertical deminsion of the lower a-arm pivot points, from a stock 03-04 cobra at ride height I believe.

          Thanks again
