65 NSS 500 OP mopar Joined: Nov 2007 Posts: 505 Northampton Pa	Hello Im looking for thoughts on how hard it would be to convert a 65 Coronet to a 4spd car. I really want to row the gears and dont race that often so I was considering going with a 4sp rather than upgrade my Auto/conv for my new motor. I will be running a 340 12.1 comp 680 roller cam etc. I fiqured to put my money toward the conversion rather than upgrading my Auto. If I go with Buying a package "Everything needed from Brewers Perfomance" Rather than try to hunt it down piece by piece the install should not be to bad? Just change out everything and weld in hump. Anyone ever do this and also how is brewers performance? any other thoughts, warnings or recomendations appreciated. I am going to run the 340 for 2-3 years and then want to upgrade to BB . let me know your thought s 5037010-kevin020.jpg (41 downloads) 1965 Coronet 500 340 40+ Passon 4sp 12.90 2.6 60' street tires

But if someone has all the pedals and needed hardware or knows a source Im open to that. 1965 Coronet 500 340 40+ Passon 4sp 12.90 2.6 60' street tires

My circumstances were a lot different, as I had to use a later K member pushing the motor back over an inch. Had to fabricate a custom trans cross member, and massage the torsion bar cross member for shifter clearance. I bought a fiberglass trans hump from Brewers at Carlisle and it worked out great. All you really need are the b body clutch pedal assy, the clutch Z bar and brackets and clutch linkage. The rest is fairly easy to come by....bellhousing, flywheel, clutch assy, shift linkage, etc. I'm not sure if the auto trans cross member will work on the standard 4 speed install. I think buying it from Brewers or such will be convenient, but will most certainly cost more than scrounging parts up. Depends on your time line I guess. Yeah, it's got a hemi........a REAL hemi.

The only negative I see in that is that I don't know that I would want to race at all without a scatter shield. I like my toes and feet right where they are currently located. Even if you only race a little, it only takes one explosion to ruin the rest of your life. All that being said, go with a 4-speed, you will have lots of fun. Mike

The quicktime requires a 130 tooth flywheel. If you want to stick with the Chrysler A833 then take a look at Passon Performance and his 18 spline OD transmission. It's a bolt in deal. If you want an H-pattern shifter then get a Hurst Billet shifter. It's a bolt on also.

You may have to hunt down a 4 speed cross member or get one from Brewers. On second thought.......what motor came out of it? If you are going with a 340, and had a standard 318 poly, the mounts may not be the same. Maybe a call to Schumacher motor mounts should be in order. Quote: Thanks, I agree on the scattershield.

One problem I did have was when I repalced one motor mount the drivers side. The one I got from Autozone was a little different than the one that came out like a 1/4 inch and I had problems getting it to line up. The pin thats goes into the frame dont line up. Not sure why? 1965 Coronet 500 340 40+ Passon 4sp 12.90 2.6 60' street tires

Can I put in a non 65 trans from a 66-70 B body so I can use the same drive shaft. Do I look for an 18 or 23 spline trans and also from what body should I look for. 1965 Coronet 500 340 40+ Passon 4sp 12.90 2.6 60' street tires

The hump serves no structural service to the body. It just allows clearance for the shifter and linkage. I have mine screwed in with sheet metal screws, and it's easy to remove for easy access to shifter and linkage. Yeah, it's got a hemi........a REAL hemi.

Really, I would have thought having a continuous floor on a unibody would only serve to help with overall structural integrity. But I agree, for the stamped piece of steel you get, those tunnels are not the cheapest thing out there.

Can I put in a non 65 trans from a 66-70 B body so I can use the same drive shaft. Do I look for an 18 or 23 spline trans and also from what body should I look for. All the transmissions are the same, except for the difference between A bodies and B bodies. A bodies have a shorter tail shaft on them. With a B body you will be mounting the shifter at the forward mounting position on the tailshaft. Some long tailshafts have two shifter mounting locations, the rear most one for E body shifter mounting. The cases between the 23 spline and 18 spline are the same except that the 18 spline uses a larger input bearing and housing at the front, so the bolt pattern for the bearing housing is different. Stay away from the later model "overdrive" units with the largest bearing cover, they are not as strong as the 23 or 18 spline. The 23 spline should work just fine. They used them in all applications except for the hemi cars and the 440 six pack cars, they got the 18 splines I believe. If you do go an 18 spline, watch your bearing retainer diameter hole on the bellhousing. Make sure it is the same size as the trans. I have a Lakewood sheild on the hemi in mine with the 18 spline trans. and everything fit fine. Yeah, it's got a hemi........a REAL hemi.

According to Brewer where I bought my glass unit, the steel ones were just add ons on the assy line with no real added structural strength, again just to cover the shifters. 5038690-P1010040.JPG (30 downloads) Last edited by 65HemiCoronet; 02/20/09 12:21 AM.
