4.0l throttle body swap help

I am swapping the throttle body on my 2.5l for a 4.0l. I swapped all the sensors and noticed the 4.0 throttle body won't fit on the manifold because the IAC valve housing (the one thats removed with tamper torx head) has a metal tab that blocks it from sitting flat. When I removed the IAC valve from the 2.5l throttle body, both of the bolts snapped from being rusted, so now I have no way of installing the new IAC into the housing. I was just wondering if it was possible to buy a housing that the IAC valve is screwed into.

Personally, I wouldn't go to the effort. You won't really see the benefit some people claim you'll get from that conversion... most of which is probably the Placebo Effect in action. Jp Magazine at one point said they might have even noticed a slight loss of performance after installing the 4.0 TB.
When you have a choice, buy American.

Only really worth it I'd you've upgraded the 2.5's intake, exhaust, plugs, heads, and so on and so on. Pretty much enough cash to have swapped to the 4.0 But let us know what you get outta it. I like hearing about ppl trying to squeeze as much outta the lemon they have.
