Do they make a spacer ring in case you have an early small bearing trans in a later big bell housing?
I ask because a guy gave us a early Corvette M21 and a 10.5 bell housing
We swapped a bigger bell housing and an 11 inch clutch, is that going to be a problem?
I /we never thought to check the diameter of the bell housing hole v/s the input collar of the early Muncie
TO THE BEST OF MY KNOWLEDGE, No, there is no spacer collar ring to adapt a 63 front bearing retainer to the hole in a 55-62 or 64-latere bell housing.
As I mentioned earlier, the easiest and simplest way to adapt a 63 transmission to a 55-62 or 64-later bell housing hole, is to round up a 55-62 3sp front bearing retainer and bolt it to a 63 T-10 or 63 Muncie.
As far as bell housings are concerned, ALLLLLLLLLLLLLLLLLL Chevy bell housings have the SAME bolt pattern to mate them to ALL Chevy V8 engines and they all have the same bolt pattern for mounting a 3 or 4sp.
Now that we have gotten into this--------------------------- and it WILL NOT MATTER TO MOST PEOPLE ------------------ here is some differences between the 63 T-10 and 63 Muncie compared to the 64-later 4spds.
Here is a comparison between the front of a 63(left) and 64-later Muncie front face. Notice the hole for the front bearing of a 63 case is smaller. Also, the bolt pattern for the 63 front bearing pattern is smaller.
This shows the smaller diameter 63 front bearing retainer positioned in the hole of a 55-62 or 64-later style bell housing. Notice the gap between the retainer and the opening of the housing.
This is a 55-62 3sp front bearing retainer in the same housing. Notice the retainer is a full fit.

55-62 3sp bearing retainer on 63case. Notice it has the larger diameter to fit into the hole of a 55-62 or 64 later bell housing, but has the smaller bolt pattern to fit a 63 T-10 or 64-later Muncie.
64-later front bearing retainer on a 64-later Muncie case. Notice there is more surface on the face of the 64-later Muncie case than there is on the 63 case(above picture), BETWEEN the edge of the retainer and the outer edge of the case face.
As I said, this will be of no value to MOST people here (T-10s and Muncies are fading away and being replaced by 5 and 6spOD trannys).
