215 Buick Cam set Material= B-1; Part No. SH-475S

This kit (from the back of the catalog) includes five bearings details
are listed as follows:

Set No.     = SH-475S
Undersizes  = Std. Only
Set Contains
1-SH-475; POSITION = 1; Dia of Journal = 1.7850/1.7860; Housing
bore=1.9155/1.9175
1-SH-503; POSITION = 2; Dia of Journal = 1.7550/1.7560; Housing
bore=1.8855/1.8875
1-SH-363; POSITION = 3; Dia of Journal = 1.7250/1.7260; Housing
bore=1.8555/1.8575
1-SH-364; POSITION = 4; Dia of Journal = 1.6950/1.6960; Housing
bore=1.8255/1.8275
1-SH-365; POSITION = 5; Dia of Journal = 1.6650/1.6660; Housing
bore=1.7955/1.7975

Oil Clearance = 0.0010/0.0060
Max. Wall     = 0.0643
Max Length    = 0.760


As far as other engines using any of these.  The usual suspects. 
Catalog list includes British Leyland 3.5, Pontiac 215, and Olds 215.

Others that use some of the bearings include

Bearings SH363, SH364, and SH365 are used the last three positions in
1956-1966 Buick V-8s (56-61 - 364 CID; 65-66 - 400CID, 59-66 - 401CID,
63-66 - 425 CID)

Bearings SH506, SH363, SH364, and SH365 are used on 1962-1967 Buick V-6s
(64-67 - 225CID, 62-63 - 198CID,  

Set of Buick 64 - 67 - 300CID and 340CID are the same except for bearing
No.1 which has oil clearance of 0.0005/0.0055 and a wall thickness of
0.645.  This front bearing is also used in 67-7950,400,430,455 Buicks
(which use different bearings in positions 2,3,4,and 5) and on 76-84
Buick V-6 ( 181,196,231,252).

Looking it over if the bearing set is no longer available (doubtful with
Rover still in production) the front bearing from the late model V-6's
should be usable up front, the rear 4 bearings maybe harder to find
since no GM product used them since 1967.
