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

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:

But is that stiff enough for us using who are still using t-bar suspension? They went alterkation on that dart sport.

you say "into a "T", but wouldnt an H be more appropriate? or am i mis-interpreting this concept
IE: see my crappy paint art of the sub-frame


Hopefully this isnt construed as hijacking, i think its still pertinent to the 42rh swap.

One more Q: is there a size difference from the 42rh/46rh or is it just different internals?
