To buy this duster or not??

that car would sell in a hurry up here. Anyways, slant is no big deal. 150 bucks for /6 to V8 mounts and K frame is fine. 7 1/4 rear is not heavy duty, but I've beat on them with mild 318's and never lost one.... ever. In fact, the "low dollar 318" Duster I have was a slant. still has the 7 1/4 rear with 2.76 gears. All is fine, and it's for sure has had it's share of abuse.
Brakes, gets some disc off of a diplomat, aspen, volare or something of the sort and there is your disc brake conversion.
yeah, I'd buy it
