79- down ford trucks work well, and 89- down dodge vans and trucks work too. Make sure the housing says "60" on the lower rh rib on the center housing near the cover and it has 3" tubing, and you will be able to install mopar ends and keep your Wilwoods. You will have to be quite sure to square up the ends of the tubing as there's no margin for error, so measure twice and cut once! As far as a pinion snubber mount, you can weld and machine, or fab a mount.
