TKX clutch assembly question
I plan on swapping a TKX 5 speed to go behind my 1977 4 bolt main 350, which I believe is a two piece rear main seal. What is a good streetable flywheel, clutch, and pressure plate combo for my application? thanks!

Re: TKX clutch assembly question
My numbers will be a touch below that, but a little overkill will give me some wiggle room to play if I decide to add some more! Do you have the part numbers for those parts? Thanks!

Re: TKX clutch assembly question
Here is a couple of numbers. the flywheel I used was the Ram 22 lb. one part #1501LW. if you want the 30lb. one it is #1501. The clutch I used is a Ram 88764 HDX. I don't know if you are going from an Auto to a manual But if you are swaping , you might take a look at Hawks TKX conversion kit , it has everything you need. Have fun , mine works awesome.
