After putting Caltracs on my car (stroked small block, 5k converter), it crushed the axle tubes at the spring perches on my 8 3/4. I switched the housing out for a Moser MO875 fabricated housing with a back brace...everything has been great since. This is on my 3200# Barracuda street/strip car that runs mid 10's.
67 Barracuda street car, 408, e85, 1.38 60', 6.44 @105.9 in the 1/8 mile, 10.19 @130.5 in the 1/4...so far....
