No response to the question if the bellhousing is original. Misaligned bellhousing equals popping out of gear and gear grinding.
Forget the pedal free play and do like the FSM says, set the play at the throwout fork at 5/32".

Awesome looking Swinger, my buddy has almost the twin to yours, his has a black interior!!! I'm having similar problems with my 67 hemi GTX, starting to break it down to being the pilot bearing being too tight and turning the trans even when the clutch is depressed, I have had my buddy with the Swinger go through the trans it and it seems that it's real good for a while and than it starts doing the same as what you car is doing, being a nice guy that I am I believe putting some grease on the pilot shaft is creating some of this problem after a while as well as not pre reaming out the pilot bearing, what I have been reading ppl say to not put any grease on the pilot bearing at all, I have used just a dab of lithium grease, my next step is to use a bearing that goes into the A/T torque converter hub area in the rear of the crank, this should be the part number, # BRG FC69907, hope to try this in the next few months. Good luck to you,

Alot of good replies but none of them garantee you input shaft/disc is free. With the car running, press the clutch pedal. After 5 seconds try to engage reverse. If the clutch was disengaged it will eventually stop spinning allowing you to engage reverse.
Although my feeling is the problem is in the transmission. If you do not disengage the clutch and try to shift. The gear should not be allowed to go in. Similar to shifting without a clutch. It either goes in when the speeds are matched or it's not going in, but there is no grind.

Once you get it measured, then get the ROBBMC dowels that will get you realigned. I tried all of the others, its the only one that works.

I'm a newbie on this but I cant help wondering if there is any way to pin it down to either the clutch or the trans before having to take off the bell to check runout there? But that IS what we have been trying to do here all along. keep us updated

It's clutch related, and he hasn't answered the question of the originality of the block and the bellhousing .
Chrysler did the final machining of the crank main line, and the pilot hole of the bellhousing, with the bellhousing bolted to the block. The assembly stayed together from that point on. That is why there is a big cover plate on the bottom of the bellhousing, so it could be assembled with the bellhousing in place.
Most people have bellhousing that were not original to the block in the car as most cars are not matching numbers, so there is a runout issue that many do not realize they have.
running up my post count some more .
