I have a '71 240 where I am trying to get an R200 LSD into. I purchased the Arizona Z moustache bar and had the front diff crossmember modified so as to move it forward to mount up to the body.
So here is the problem, the setup is too short! I raised the diff, mounted the moustache bar, went to the diff nose to bolt it to the car and it is about an inch away from the mount holes (aft) on the car. In frustration, I took the diff out, unbolted the crossmember and mounted it to the car so I could install the control arms. Any ideas as to why this is? Also, any thoughts on how to remedy? If need be, I could remount the diff and take some photos (but I wouldn't be thrilled). Thanks!
