I have a tko600, I cut trans tunnel out and raised id it to clear trans, I never actually checked my angles but I must have gotten lucky as I have zero vibrations, I used a modified stock crossmember to clear dual exhaust and moved the trans mount. I also have a 52 F1 Ford that I gotta spend some time on as it does have some kind of vibration from the driveshaft, I hate dealing with driveline angles, It sounds simple but correcting it isnt.
Installing the TKX and hit a snag

I put a TKX in my SS and had no clearance issues. I did have driveline angle issues but those were resolved with the right trans mount and adjustable upper control arms in the rear.
I can fit my hand all the way around the top of my trans and not hit anything. Clearance was amazing. I went with American Powertrain, though, because I didn't like where the other options put the shifter. I wanted it to come up through the console.

Yeah when I installed mine I had clearance issues with the clutch fan making contact with the shroud and the header collectors being closer to the floor. A 1" spacer between the transmission mount and the transmission resolved everything and got my drive line angle back where it was prior to the transmission swap. My TKX is a modified one from Silver Sport that has the shifter in the stock 78-81 4 speed location. My clearance issue was with the shifter to the shifter hump opening. There was one spot to the right and to the rear of the shifter that needed tweaking.
The use of loving persuasion. If it doesn’t go in with some sort of difficulty something will go wrong in the most Aggravating of ways. Then you end up fully disassembling it again for some minor thing. Think of it as the art of building a car.
I took it for a 35 minute drive the other night. I had it up to 75 mph with no vibrations or rubbing noises. The only thing to do now is address some sound deadening issues around the shifter hump.
I used the Spicer calculator and played around with the pinion angle to get the u joint operating angles as close as I could. This is what ended up working for me.

6 deg is too much. Universal joints are not constant velocity joints. In one revolution they will speed up and slow down like 2 times. This creates a humming type of vibration.
Also pinion up is no good since the rear housing wants to point up during acceleration. If anything, it should be down a bit. Ideal 1 to 2 deg max. With a matching angle at the front.
Keep the rockers out of the equation. It's trans output in relation to driveshaft. Then driveshaft to pinion shaft.

No, but you obviously didn't read the entire thread. But I will save you the trouble. I resolved the problem by concentrating on achieving ideal u joint operating angles and eliminating vibrations.
