: I don't know everything about clutches but what I do know is that the "long style" pressure plate is a better performance piece. However, it doesn't fit the late model bell housings without altering the throwout fork. You say that you have a 68 trans and a mechanical equalizer bar, both of these pieces are not original pieces on your car. What bell housing do you have? The bottom line is that the long style pressure plate sticks out further, requires more throwout bearing travel, and additional force to disengage it. If your linkage was designed for/set up originally for a diaphram pressure plate, it would not produce enough throwout bearing movement to properly disengage the long style pressure plate.

: : I am using the "long" style "finger" type pressure plate. The diaphram is more desirable, but I don't have it. You say to "stick with a hi-po diaphram pressure plate", but thats what I want to change to. I am using an equalizer bar linkage, with a 1968 Toploader 4-speed. Thanks for the help, maybe this info will help you give me better advice -CP

: : : Need another clutch, again? Are you sure you had the clutch set up right? If you use a performance clutch or pressure plate without going to a billet flywheel, you'll have trouble.
: : : I've been dealing with RAM clutches out of South Carolina and have had good success. Their tech people are excellent and were able to rebuild my clutch and pressure plate to my specifications (www.ramclutches/803-788-6034). Their catalog lists a number of clutch/pressure plate combos for your car ranging from the Power Grip clutch/pressure plate (mild engine mods/no slicks) to Super Duty Performance cluch/pressure plate (considerable engine mods/slicks).
: : : Unless you're going for all out performance, I wouldn't mess with moving the throw out fork to accommodate the larger pressure plate. It's a hassle to get the proper geometry. Stick with a high performance diaphram pressure plate, a good clutch, and invest in an adjustable clutch cable from Summit of BMX.
