Hi everyone
I am in the process of assembling my front suspension, it is totally in bits, my question is with the front lower arm laying flat on the floor what is a rough measurement for the rear arm from floor to hole in end of cross member arm? Just want a rough estimate to get it somewhere near to standard ride height before assembling on car
Thanks

I don't know off the top of my head, but it is in the workshop manual, and the Haynes version of it too.
