Allow me to clarify. When the steering controls (Drag link, steering gear box, tie rod ends, etc.) are in front of the engine cross member, the car is a front steer car. When it's all behind the crossmember, it's a rear steer.
When pulling your drive train out of a front steer car, NO-THING fits into a rear steer car. Every time I turn around, I have something hitting the freakin' drag link, ...or gear box, or tie rod ends!!!!
It took me a while to bolt the engine in because I'm poor and needed a new oil pan to clear the drag link. I took the cheap way out and notched the oil pan to clear. Ok, the '67 has welded tabs to mount the trans cross member. Since a power glide is MUCH shorter than a Th400, I had to cut those off, move them back, and weld them into place for the new trans. I have a set of Hooker headers for the engine. The passenger side slid right in. The driver's side required some "clearancing" to get around the dang gear box. Then once I got the headers in, I checked clearance on the tie rods. ...........They hit when you turn the wheels more than 10 degrees. No way around it this time, I either build a set of headers, or buy a set. (Leaning toward buying, building headers is not my favorite job)
Did I mention I'm starting to HATE this rear steer set up in the Impala??
Newbies beware, your Chevelle stuff WILL NOT fit in your Impala.
