77 cj-5 help!

I need to know if there is a good website or online manual here that can tell me how to install a new clutch in my 258 1977 CJ-5. I went to the parts place and asked for a new clutch and they said there is 2 different clutches and i wasnt sure which one i had. Does anyone know what im talking about here? Also buying a clutch from a parts store here in town a good clutch or should i buy one online?

 

I have a 78 and with the 304, however, the service manual does not differentiate between 6 or 8. I can send you the 15 pages dealing with the clutch, scanned in PDF format it is a 42 meg file. I don't think the PM section can handle a file that size.

On to the question at hand. I have had both 10.5 and 11 inch in my Jeep the flywheel in the 304 is drilled and tapped for both sizes. I'm not sure about the 6, maybe someone else will chime in.
