Sorry it’s been a while for the Dart. Been finishing up my 64 Savoy to take to MATS last weekend. Took 2nd place! I’m very happy with that. Ok, I got the transmission cross member front US Car Tool for an A518 46RH and removed the trans loop. I left excess metal on the loop and the bent them over the top to close it off. I will weld them up and make it look clean. The mount fit ok, I had to trim a little to fit but not much. You can see in the pictures the little dips I grinder in the top of the bolting plates. Need to get a bare 46 RH housing to test fit with block and HDK member.
