42RH / A-500 in a Duster with pictures.

I've got two questions:

1. I see a people hacking that center piece and using a plate to make the new support, how thick does that piece need to be?

2. what's the difference between the 42rh and a500?

If I may add, sub-frame connectors should negate worrying about replacing the tunnel 'U' piece you cut out, especially with a beefy stock style cross member either fabricated like gdonovan did, or, connecting the cross member into the frame connector in a 'T' type fashion like so:

Taken from an episode of powerblockTV stuffing a 426 hemi into a 74' Duster. Crossmember fab comes in at 6 mins or so, which also gives detail on wall thickness of steel used:

I've gonna say, if it's strong enough for a 426 new Hemi, it's strong enough for a 360 running a 42RH. :glasses7:

:burnout:

Also found another style of cross member fab on this episode:
