I'm using an A883 O/D out of a mid '80s slant six truck in my Newport with a 1970 B body pistolgrip mechanism and mounting pad.

Rods I made from the chopped up truck and A body rods and I think I used B body levers. I probably could have just bought the rods that matched the shifter and only had to do a little massaging, but I was out of $$$.

I mounted the trans to an engine stand and made the linkage. I wasn't playing around doing it under the car. I made sure it shifted smoothly and went fully into gear without binding before I installed it.

Over all, it wasn't to hard at all to make work perfectly.
Most of the stuff I had to buy new I purchased from Brewers. I used one of their new aluminum bells for the 130 tooth flywheel with a 4.80 hole along with a new 4.80 bearing retainer for the 308 bearing.

Ive been running the O/D trans for over two years now and the wide ratio isn't too bad even in my C body with a mostly stock gutless 400 and 2.94 gears. For what these transmissions can usually be had for you can't beat it. Ive had em given to me.

I have a real 1969 Dart GTS 383 4 speed car that I bought another NP833 O.D tranny from some other shop out of a 1977 or later Volare or some other look a like A body tranny. No way will that stock OEM shifter linkage work in my car The other longer O.D 833 truck or van tranny looks like it will work fine in my 1966 B body with the stock shifter mounted on the front mount I did buy a new shifter mounting adapter (the thick alumimun piece the shifters bolts onto) from Hurst but it is not a perfect fit in the shop so some cobbling will probaly be needed

I was able to get a great deal on the 4 speed so I went and picked it up today. I also got the shifter that goes with it. Does the pic of the shifter help to know for sure how this set up will fit in my car?

I called and talked to Brewer's today and they have a bearing retainer with the smaller diameter for the OD box or they said I could turn the stock one down to the correct size. I have a machinist buddy so I might have mine turned down because that will likely be free and free sounds good! I think I may go with their reproduction bellhousing. Thanks
