Is there a difference between the 89 clutches and the 91? I remember reading something about this but when I searched I couldn’t find anything.
Thanks

 

I thought the 89 had 20 splines and the 91 had 21 splines I cant remember though someone correct me if Im wrong....

 

I believe that only the 88's had a different spline count, and the 89-91 were the same....

 

hey your right...I couldnt remember...There you go

 

i wonder why act has different part numbers for 89 and 90-91

 

89's have a slightly smaller flywheel. 90-00 are the same.

 

so will i be able to use a 91 pressure plate and disk on a 89 ?

 

Im in the same boat. I bought a 90-91 flywheel and clutch to fit on an 89.

You have to change the flywheel bro. yours is 200mm, you need 212 mm

 

So if I want to buy a lighten flywheel which one should I buy because ive seen a lot of them that claim to fit any d-series 88-00?

 

buy a flywheel that specifies 1990-00 d series and you will be able to use the clutch set for the 91. or, just get a flywheel for a 90-00 - doesn't have to be aftermarket, unless you want to put the lightweight aluminum flywheel in there.
