I think the 2nd pic looks more to scale.

That's 1/8-27 NPT on the left and 1/4-18 NPT on the right.

My first thought was the neutral safety switch is loose and not moving the necessary amount or not grounding consistently. You could bypass the NSS for a few days/weeks, see if the problem goes away. Just remember the car will start without depressing the clutch :)

How loose is too loose? The new clips I got from Inline (71 ebody) average about .008 thinner material than the factory clip. The overall "height" of the clip when measured against a flat surface was about .012 flatter that the old one as well. Couple that with the unknown tolerance/location of...

Check the ground on the passenger side rear bulb. For a quick test, you can run a temporary ground wire from the bulb socket to a good ground, then see if the trouble goes away.

Check your tranny inspection cover/dust shield, ensure it's tight as well as not hitting anything inside the tranny. Make sure your exhaust system is tight, including the hangers. Check the heat-riser on the passenger side manifold.

I couldn't find any relevant dimensions listed in the FSM or the online Torqueflight manuals I checked. I thought that was odd. So I checked a couple driveshaft shops, they are listing 1.558 as the OD for their 904 yokes. None listed any tolerances (+/- .001, etc.). Chrysler 904 Transmission...

With any luck it's a bad bushing and the new one will fix your clearance issue. While you're waiting for it to arrive, I'd take a few more dimensions. Check the bushing in a few places around the ID, 12:00 to 6:00, 2:00 to 8:00, 4:00 to 10:00, etc.. You're looking for out of round. Do the same...

I believe there's an oil hole in that bushing that needs to line up with a recess in the top of the housing. Is it oriented correctly?

Something looks funky with those measurements. The yoke is .015 larger than the bore in the bushing? You wouldn't be able to get the yoke in/out with those dimensions.

Years ago in my machinist days I used these to loosen up Albrecht keyless chucks after a newbie spun a drill in the chuck and locked it up tight. There really wasn't a good place to put a wrench on the chuck to try and unscrew it, unless you wanted to put a pipe wrench on the knurled part and...

When was your last oil change? If you can't locate it with the scope from up top, before you pull the intake you could drain the oil pan and run a scope up thru the oil drain hole. You wouldn't be out much time if you don't find it down there. I'm inclined to think it's higher up in the engine...

If you haven't done so yet, check the top of the tranny. Get under the car and use a mirror if needed. Make sure it's not hanging off the speedo cable, tranny linkage, exhaust, etc..

Do you have access to a bearing mic? (I think technically it's called a round anvil mic, but I always heard them referred to as a bearing mic or tubing mic.) You can measure the bearing thickness at various locations. It would give you some peace of mind if you had the numbers.

Top pic of post 4. Here's a bigger exploded diagram from Holley's site. It's part #117 in the link below. https://documents.holley.com/techlibrary_4150_4160_exploded_view.pdf
