that will tell you about the TB and the sizes, but the bigger it is the more power you get
As for Rinex, I'll leave that to people that know more than I do.

Renix = Renault-Bendix. They made the computer/controls for the AMC Jeeps from '87-'91. These TB's are smaller (and more costly to bore) than the Chrysler "HO"'s from '91-present. I bore HO's to 62.5mm. MIKE

Save your money, bore your own tb out to 60mm. You can do this on a mill in about 15 minutes. The stock tb goes from a 60mm bore to a 55mm bore (past the butterfly). Do a search on tech articles for boring your own. I dont think a 62 gives that much more of a performance gain over a 60, and damn, the 60 comes so much easier. If you insist on bolting in and going big, it looks like XJ-armor is selling 62mm tbs on ebay that are painted all nice and pretty for about $150, not a horrible deal.

Rubicon Express makes one that looks like red billet aluminum. BBK also supposedly makes an aluminum throttle body, but I haven't confirmed that yet.

That's right, It doesn't, at least on a 4.0 anyway. A 60mm TB is all you need on a 4.0 that's limited to 5250rpm.
The advantage is probably slightly greater on a stroker but even there, a 62mm TB is all you need if it's limited to the same rpm..

Look up machine shops in the white pages where you live--I'd bet they can make it 60mm for under $20
