How does this driveline sound?

OK...in my infinite wisdom, and due to a larger than expected royalty check I have decided to give the Scow a little butt-lift.....heres what i am thinking...let me know if any of it is wrong or counter-productive:

transmission: swap my current  18 spline stuff plus a Passon Overdrive kit into a set of Passon's aluminum case and tail.
new driveshaft by Denny's...should I go with the aluminum or the 'superbeefy' steel one? ( car has 405 RWHP, and that will go up end of summer)
Rear: new dana 60 with 4.10's, girdle,35 spline axles and a possibly a True-Trac as oppossed to the trac-loc.

I had to decide today between better mechanicals or new rear quarterpanels...and I got to go with mechanical improvement this spring.

Looks good to me altough I'm not a fan of alu gear box cases...

What's wrong with the steel one you have?

[SFRT]

suppossedly the passon stuff is 'better' and 'beefier' and lighter. the set of case,tail ,panel is not 2 much dough, so I figured 'go for it'.

what are the negatives of aluminum cases?

IMo nothing, but maybe some think it is to "modern"

That sounds like an excellent plan of attack. 

On a street car i'm not sure that i'd be willing to spend the extra dough on an aluminum case but that's your call. I do like the idea of the passon overdrive gearset....that is definately worth the effort. 

On the driveshaft i would opt for steel....aluminum isn't that much lighter and is more succeptible to damage from road debris.
