Anybody know if a 63 powerglide will fit in place of a 62 powerglide. I know the 63 has more mounting bosses( 5 vs 2) than a 62, and that late 63 and 64 glides came out with tranny cooler connections, but need input as to whether the shifter on the 63 comes up in the same place as a 62 and if the 63 will mount on a c1 frame same as 62. Thanks for any input.
