8 3/4 Chrysler pro gears?

In 1988 I Decided to install a Dana 60 in my 62 dodge. I was running 11.80's @ 3700# was tired of worrying if this was my last pass on a 8 3/4 gear set, my luck it would have broke in the final at a national event. Any way I built a real 66 Dana 60 housing strange axles and spool Richmond 4:88 gears etc. never broke another part in that car. That rear differential in now in my 64 Plymouth AA/SA with a new gear set and bearings just because!
When I installed the Dana in my 62 dodge in 1988 I did it at the track (englishtown) made my first pass with the 8 3/4 , installed the Dana and drive shaft made another pass the car went .012 quicker !! My Dana was about 22# over all heavier then the 8 3/4.
I would never suggest using an 8 3/4 over a Dana 60.

FYI at the allstars race 2 weeks ago my uncle broke his 8 3/4 in his c/sa barracuda and destroyed his transmission case in the process. It is a pro trans with the band modifications etc. the case alone is 1/3 the cost of setting up a Dana 60. His car will be getting a Dana 60 this year as well.
