Again, thanks! | | | | Joined: Jul 2011 Posts: 114 Wrench Fetcher | | Wrench Fetcher Joined: Jul 2011 Posts: 114 | So I need to replace the clutch disc on my 1959 3700. It has the 235 and what I believe is a sm420. It's a 4 speed with granny low. The old one was basically gone, but the friction points look to be about 10 inches. I have one that will fit, but is 9.5 inches. Will that be a problem or will it work fine? | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | it'll fit, but for the amount of work, new would be better and original would have been 10", possibly 11" .... and FYI. the 3700 model is a forward control van, what your pics show is a 3600 3/4T pickup as indicated by the 36 on the fender emblem

I am pretty sure the 11 would be too big. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | got a NAPA nearby? best to get the complete kit and they should have clutch kits listed, mine does [1 year warranty]
