Did your "engine plate" break? In post #49 of your closeup pic of your flywheel, look at the bellhousing surface at edge of the starter hole, where is the "engine plate"? It looks like only the bellhousing is there, and the starter would be bolting to the bare bellhousing, which would causing a spacing / binding issue.
Yes there is some activity there....why isn't the plate around the starter hole?
I’ve dealt with this myself and argued that there are two starters. The starter on my truck has worked fine since I put it in, but recently a bad battery has helped end the starters life. I took it to parts store and spent a half hour trying to find the correct one. I still haven’t put it in, but it looks identical. Here is the difference between the two. One needs a spacer between belland engine from what I gather and the short one doesn’t. The short one is what my truck used.
The starter I found that matches is from an 84 ford in O’Reilly system. Part number R613162A. I have not installed mine yet but I don’t see why it won’t work like the other.
i have 78 460/4spd with l&l flywheel, factory dust shield
Also, looking at your pic where the plate is cut out, I can tell you that the starter has to be flat with bell. Yours looks like it might be sitting ****-eyed since most of the plate is gone. You need to make sure you space it evenly

I was hoping no one would see that. Like this story is not screwed up enough, here is the reason you do not see it in the pic: my buddy that is helping me with this swap is an old school farmer and rancher as well as a hot rodder. So since this truck has been stuck at the same stage for several months, we figured that it was either the starter, bell housing, or motor plate. One of the things he tried was cutting out the motor plate where the starter touches it and cutting out a new piece that was thinner to try and make it work.
He and I did not realize what critical tolerances are involved in making this mesh together correctly. So I cannot say we made it any worse but we did not help it any. The whole swap was really easy until we hit this snag and again it has been sitting about five months and we are both really frustrated with it.
I have sent the picture of the fly wheel to Alan over at L&L and if I have to put a new ring gear on it he said that was relatively easy to accomplish with a torch.
Really appreciate all of y’all‘s help I feel like once we get the stock stamped 351m/400 rear plate that we will be golden.
There is a later model 460 engine plate for sale on eBay right now but I don’t think that is what I am looking for. Anyway I have looked at eBay and will start calling some salvage yards around Central Texas but I might even have to buy a parts truck to get this resolved. Alan at L&L said there was a company that makes stamped aluminum ones and they might work. He feels like the key is not buying a plasma cut one as the tolerances are too exact for that type of product.
Nothing special about a C.J. flywheel. Just a cast, not billit, neutral balance. I'm pretty sure they are drilled for 11" clutch & long style psi plate. kind of a draw back, compared to whats available out there. I run a billit steel 12" Ford flywheel.
Edited:
it's been 30 years so the details may be a bit fuzzy. I removed the BOSS reference and labeled it as a SCJ.
here are some pics of a 69 or 70 429 SCJ flywheel and replacement clutch. note the pressure plate has 12 springs. disc is 11.5" spline is 1-1/16 x 10. the outer 12 holes are not threaded.
there appears to be enough meat left to drill holes for a 12" clutch. I'll have a machine shop decide when the time comes.
don't have a starter yet. the disk is too small for a ZF5 input,,,1.25" x 10 splines.
these parts have been lovingly stored in my basement for over 30 years along with the dis-assembled 429SCJ/460.

All Boss and for that matter SCJ too use a large spline input shaft and that disc in pic is smaller. Looks like maybe for a 435 ? . The fly wheel makes me think with that tooth count that it just might actually be a 390 truck fly wheel ? I think they were 11.5".
I removed the Boss reference, left it as a SCJ. disk is 11.5" splines are 1-1/16 x 10. that's what some sites now say fits the '70 429SCJ.
thinking about it for a while, the engine came to me with a steel scatter shield but no transmission. it may be a bit late to assume that's the original flywheel.
C9AE-C may give somebody a clue about it. some time around 1986 I was going to put the engine in a 1977 F150 4x4, with a NP 435. that's probably why this particular disk
was selected.
Here are some pics (I deleted them) of a genuine 69 or 70 Boss 429 flywheel and replacement clutch.
The flywheel makes me think with that tooth count that it just might actually be a 390 truck flywheel? No such thing as a truck only FE flywheel.
C5AZ-6375-L .. 390 Flywheel - 184T ring gear - Use with 11 1/2" clutch / (6) 5/16" -18 pressure plate attaching holes on a 12 7/8" bolt circle / Obsolete
1965/71 Ford Passenger Cars // 1968/76 F100/350.

But this is not an FE flywheel, it's this: C9AZ-6375-C .. 429 Flywheel - 176T ring gear / Marked: C9AE-C / Obsolete
