I have an 85 Chevy k10 with SM465 and was told that the countersafts came in 2 size on the input side 1.3” or 1.4” for later years. Mine is 1.4”. I’m looking to get another case to swap all my parts into and found one out if 78 k10 but don’t know if the counter shaft is different size or if it even matters if it’s just the ID of the bearing that’s different and case is the same. Are the cases and tops interchangeable for my 85 and the 78 I’m looking at. Info and knowledge needed. Thanks.
