Just put one in a 76 D100 360.... do yourself a favor and go find a 90-93 crossmember and spacers all you have to do is blow holes in the frame it's a bolt in deal! I had to make a few modifications with a ball peen hammer to the floor pan. But that could have been due to floor pan replacement previously. If You find more than one cross member and are going to be going to the Mopar Nationals grab one for me I scavenged 1 out of my 2 wheel drive Ram charger for my kids truck and now I am short said crossmember. Make sure you get the later version 518 with lockup, there's a 3 pin connector on the driver side is as opposed to to be non lock-up ones with only two pins.
