Pre 82' RX7 Clutch?
Are the clutch's from the early RX 7's the same as the ones used in the Rotary pickup's? I apololgize since this is RX 7 forums but I am looking to replace the clutch in a 1977 REPU with the 5 speed transmission and have found that the truck has the 8 7/8" disk. Everything I have found at the local auto parts stores for the 1977 Rotary truck appear to be the smaller disc clutch's with no reference to the 8 7/8". Did the early RX7's use the bigger clutch set? If anybody can help me out I would greatly appreciate it.
Thanks,
JD

I found this,I don't know if it helps.
Maybe see if Bumpstart( the poster) has any knowledge of the Repu.
Also check the Old school and other Rotary section.

( actually 235mm for s5 and 245 mm for s4, but they interchange )
and is 23 splines
the pressure plate is mounted to a flat faced flywheel
( actually the inner friction face is a few mm higher than the bolting face )
prior to 1983 ( in most markets, HB cosmo has the 225mm clutch in 1981 )
all rx's used a 215mm ( 8.5 incher ) with same 22 splines as the NA
and the friction face is stepped about 5-10 mm lower than the bolting flange face

Yes that does help some. The N/A, first one listed, sounds just like the one I have pulled from this truck. What worries me is that the bolt pattern will not be the same on the flywheel's of the RX7 and the truck. Otherwise I would just go ahead and buy the clutch kit for the RX7.
