Is this any good or will it work for my 73 duster?

Bryce,

If your car has disc up front, the rear wheels won't fit as the axles he has will likely be small bolt pattern. It will fit your car, no problems except maybe a driveshaft change/alterarion.

Not a bad deal, yopu could also redrill the axles and a set of SBP drums to big bolt and have a usable rear.

You won't hurt a 741 case. The "they are weak card" is way overplayed.

I'd see if you can get everything for $400 or less, then sell the 489 case for 50-75. It's a decent deal at the sellers price if the axle bearings are good.

I'd buy it...

Same seller had a BBP disc set up as well not long ago and it was really well priced from a value standpoint.
