LUK Clutch kit question!!
There are 2 LUK Clutch kits one is 04-084 and the other one is 04-021, which is the correct one to use on a 1963, 327 Small Block engine?
I have read the various discussions but am more confused now!
The LUK (Shaefer) Site only lists the 04-084 as the correct model, yet I understand that GM changed the clutch in 1963.

Not sure of any difference, but I put the 04-021 in my '67 327/300hp. All has been well for 2700 miles.

The LuK catalog recommends kit # 04-084 for a ’63-64 and kit # 04-021 for ’65-67. The difference is the clutch disc – the 04-084 has a 10” disc and the 04-021 has a 10 3/8” disc. Both discs are 10 tooth, 1 1/8” splines. I couldn’t find anything about a difference in pressure plates. I remember reading “debates” over early midyears and the use of 10” discs. You probably can’t go wrong following the LuK recommendation but maybe someone can chime in about the 04-021 fitting a ’63 or not?
