I own a stock 1979 dodge pickup 2wd 3speed manual trans. I think it's an 11 inchdisc.,1' spline and a BORG &BECK 3 lever diaphragm. A clutch expert from one of the major US Manufacturers said",If you want a HD clutch for your truck,you could upgrade to a 12" clutch as the covers have the same outside dimensions." Should I spend the extra $50-100. on a bigger clutch? THANKS Guys!!

alot of the clutches are made that way so that you can put a bigger clutch on the same flywheel.... yeah, a bigger clutch would be better especially if you use the truck AS a truck what gets me is the difference in price... shouldn't be that much, if any. that is unless the stock repl. is a reman and the biger one is brand new.... apples and oranges here. anothe possibility (if were talking reman) is that he's trying to "stick" you with the core charge since the 11" is not a 12" model, and some are sticlkers for making sure that what you turn in as a core is the same as teh parts you bought.
