Hey guys - thanks for the comments.....

Average highway speed limit out here is 65. <-- That's my goal. My days of street racing are long behind me.

Taller tires are out. These are as big as I want to go. I'm running 235/75R15s with a total height of about 27.5-28".

If the truck *does* have the 3.73 rear end, I guess I really should be okay. If it has the optional 3.07 or 4.11, I'm borderline. Reckon I just need to pull the cover off and count teeth to be sure.

I've got a guy who can do a rebuilt 700R4 and gear swap (he recommended 3.08) for about $2500.

Thanks again!
