these are the more common G.M. clutch disc alignment tools, they come in handy during the clutch install, by making sure the clutch disc is centered over the crank center line, making getting the transmission installed into the pilot bearing much easier
These plastic or steel pilot shaft guide tools are used to align the clutch disk as the spring-loaded pressure plate is installed. The transmission's drive splines and pilot shaft have an identical shape. A number of such devices fit various makes and models of drive trains, but you install the disc and tool and only then tighten the pressure plate assuring the correct pilot bearing and transmission input alignment
When you go to install the muncie transmission, you'll obviously want the clutch disc lined up correctly with the clutch alignment tool, and the pressure plate bolted on the flywheel, then remove the alignment tool after the bell housings ready to properly install, ID start with a clutch disc alignment tool being removed once the then Id get the bell housing lined up, ID install two 3" long studs
that have the same thread as the muncie trans retention bolts in the bottom two bell housing bolt holes, so you could get the majority of the weight off the trans front and get the spline close to lining up, use the two top bolts to clamp in to the bell housing before removing the studs and replacing them with bolts

obviously this is slightly off center
Pilot bushing clearance to trans input shaft should be .001 to .004
...with .002-.003 being considered about ideal,and the common brass pilot bearing
should be greased on install, but manufacturers parts vary and .005-.006 clearance to account for a bit of bell housing miss alignment and heat expansion is common.

if you do lots of clutches a universal tapered shaft multi diameter pilot, alignment tools a better choice and fairly cheap to buy

DIAGNOSING CLUTCH ISSUES
many times clutch chatter is the result of an un-even flywheel surface, any decent machine shop can surface grind the existing friction surface a few thousands to correct that issue.
clutch chatter is the result of un-evenly applied clamping surfaces, usually a high spot(S) on the clutch pressure plate its housing or the flywheel surface, , but heat warping or a broken spring or mis-aligned spring will also cause this symptom.
if the clutch vibration does not go away once the clutch locks up,
you've more than likely, got a drive line component alignment or rotation assembly or drive line balance issue.
you'll want to verify the flywheels mounted so its not wobbling, it may be warped, or the crank flange its mounted too has been bent or theres debris between the flywheel and crank flange, you,ll want too use a dial indicator mounted on the block and rotate the flywheel to find out, if the flywheel friction surface or outer diameter ,changes its distance from the block as it rotates
