I got a 70 Belvedere Wagon with the /6 and a 3 speed tranny.
I found out the hard way that a similar tranny from a V8 don't work real good.
I forgot the old adage- "Measure Twice, Cut once"
I wasn't cutting nothing but I forgot to do some preliminary measurement before installation. That story can end here...

What I need for the matching replacement is:

*23-1/4 overall length of casing
*15" Tail Housing
*Inspection Cover on the top side
*1-1/8" Diameter output output shaft
*26 Spline

Any help on the info I need would be paid forward ASAP

Thanks,
Rennie

Code D11 in 1970 was for the A903 3psd column shifted manual tranny.

Given the overall length to be 37-38", you most definately will need a B/E body 3 speed. Since A903's and most 3 spds in general weren't exactly warmly regarded you may need to find an alternate model of the same length. It might be easier to find a 1970-1974 B/E body A230 3spd with the side plate...(someone swapping to a 4 speed may have it laying around as a spare), the advantage to this model is the synchro 1st gear.

www.car-part.com shows a few 1966-1970 Plymouth Belvedere/Dodge Coronet A903's available in other states but yours...(Dart/Valiant is not the same)...Looks like side plate 70's A-230 from Chargers/Satellites are available in Arizona and Missouri as closest listed.

Craigslist maybe the next best thing to search or put a local want ad in...

Good luck,
