are 8 3/4 junk now?

My pumpkin was out of a D100, it had a 3.91 gear set, but no SG. Bought a SG later and moved the gears over. I spent 100 bucks for the A housing 10 years ago and another 50 for the SG w.no gears, whole pumpkin was 45 bucks at the yard. $195 for a 3.91 489 SG aint bad, but it is a conehead ;-( reused some old axles, cant remember where I got those. The B and C axles sometimes dont cut down as they are tapered where the A should be splined. I think most C's are straight. pre 80 RWD Mopars in yards out here are like finding hemis
