Yep I'm narrowing this one anyway, so I'll weld the tubes at the same time I'm doing the housing ends.
Doing a "non taper" 30 spline C-clip Moser axle deal (stronger than a stock taper axle) as that is good enough for these power levels and the fact that the car only weighs 2800 lbs. Along with the true trac, and a billet 1350 yoke setup it's honestly overkill for a 500hp street car. It'll see sticky tires and a bit of track time and that 8.5 won't even blink. I didn't want to waste any of my spare 12 bolts for the project and knew the 8.5 was plenty anyway. |

Taken to school here, again!
Having broken several 10 bolts (8.2s / in early A bodys) I learned not to push them hard and to consider all 10 bolts as weak. Clearly the capabilities of the 8.5" 10 bolts was unknown to me. Glad to learn from the experience of others. OK so for this 72 TA 4 speed 450hp with street tires does it need modifications to insure it won't break? |

Should need to modify anything if the internals are in good condition, might be worth having it inspected & replace the bearings if its original high miles before beating on it too hard. a stud girdle cover is cheap insurance too. |
