I know that I might be asking some dumb questions but here goes;
What is the deal with the 8 inch rears, which ones would be the best to use with the a-bodies. Do these rears hold up to much HP? Just asking cause a buddy of mine has an 8inch out of a 67 mustang that he will sell cheap. It has the axles and housing and pumpkin [no backing plates or drums/brakes.] Are the 8" rears alot lighter? [than say an 8 1/4] I guess they would be easier to find it seams. Which ones are the more narrow ones? mustang, maverick, pinto?
What about the center "register" on the axle flange. is it different?matter?
basically, what are the main advantages to using the 8"?
[guess the dropout chunck would be one advantage]
{hey, I'm answering my own questions.....thats ok I frequently talk to myself and answer my own self, LOL} Im losing it!!

The Good Life.

The Maverick 8" rear will more or less drop right in, without any hassles, on an A body.

Advantages

• right bolt pattern
  relatively light weight
  durable
  easy to get parts (including new gears)
  easy to install

Disadvantages

• need a conversion U joint
  Need the bigger U bolts and shock plate
  Ford product, and will have to suffer some embarrassment
  ball bearing axles are probably not as strong as tapered bearings, if you are really going to do hard road racing.

You don't need to use conversion U-joint have ford end put on your drive line. Over all length might be different measure to make sure, and check the length of the axle, that is the over all length from flange to flange where the wheels bolt on.

Getting the right one is very important. '67 Mustang (59-60" flange-flange) is too wide for any RWD wheels, even late model Mustang wheels. You might get it to work with some FWD wheels with even more offset (like >+40mm offset)

Best ones are '64-66 Mustang, Mavericks, and Granada/Marquis. Granada axles are 58" flange-flange and the others are about stock Mopar width (56.5" or so). Granadas are the ones to get to use Mustang wheels.

Too bad you didn't peek under my '68 Dart at Kearney since I have a Maverick one in there...

Supposed to be good to ~350-400 HP, so fine for us, and weight is at least 30lbs less than an 8.25" or 8.75" Mopar axle.

Please do a search on this site and there will be a lot of info.

Make sure you check the gear ratio. My son's '77 Monarch had a 2.47:1 gearset.
