74 was the last year for 8 3/4 in A body. They went to 8 1/4 in 75 and up.

The '66 D/Dart and late year 235hp cars had the 8 3/4 I bought one from the local Dodge dealer to replace the 7 1/4 that blew about every time I power shifted the 4 speed and that was with a 225, your right the small bolt pattern is least desirable and the '75's got the new 8 1/4.

Thanks for straightening that out, wouldn't want bad info out there.

In response to someone's question about "A" body 8-3/4 housings,
yes they are harder to find, yes they will cost more to buy, BUT
you can take a 8-3/4 out of a truck, a "B" body or "C" body and
have it cut down to stock "A" body measurements and then just
add aftermarket axles and either a "sure-grip' (lock-rit) or a spool.

I've had 3 of the cut down truck and "C" body housings done in
the last few years. The shop I use charges about $250 including
new spring pads. If your a good welder I suppose you could do
it yourself with a cut off saw and make a jig to hold it all in place.

Back in the early-mid 70`s I used to own a 65 Plymouth Valiant Signet with a 235HP 273 "Commando and a 4 speed. It had the small 7 1/4" (2.91 posi, I believe), that didn`t last very long at all.I knew a couple of other guys with similar 66 Valiants, and their cars all had the 8 3/4" rearend. Since I had 1 laying around, I swapped in a 9" from a 59 Ford station Wagon instead, which bolted in. These cars also had a tiny 9 " clutch and that weird "ball & trunion" driveshaft. At least the driveshaft flange kept the fluid inside the trans during the frequent clutch replacements! Throw in MoPars left and right threaded wheel studs and lug nuts,& tiny drum brakes,& it`s no wonder I went to Fords!
