65mm Throttle Body?

I need a new IAC valve, so that's gonna run me around $70 for the Mopar version anyway. I found a 65mm Throttle Body on craigslist less than an hour away, and all the valves are included for only $75. Since I need a new IAC valve anyway, I may as well risk the $$$ and just get this TB right?

He says it came off his Rubicon, but I can't find evidence of a 65mm 4.0 Throttle Body anywhere online. Is this legit?

I thought 63 was pushing it, plus you'd at least have to bore out your intake manifold too.

65mm is too much. I don't think the stroker guys even run them that big.

I think practicality ends at 63mm and even then you'd better have the intake, exhaust, and intake manifold bore to go with it otherwise its potential is wasted.
