87mm tb, what did they come in? I bought an LH6 but don't have the throttle body. Reading the info thread on the LH6 I saw that it came with an 87mm throttlebody. I've been trying to find a tb for replacement but unsure which one to get and I spent all day searching for a solution. I found one on ebay that says its for an 04-07 rainier and the part# is 12570800. Apparently if I buy a corvette one I'll have to figure out the pin outs and use an adaptor harness or pay some company $200 for cable splicing. I believe this is for the 78mm tb that came in all the 03+trucks, vans, suv's. So where does one go to find the 87mm electric throttlebody? I'm afraid that buying a 78mm is going to choke the engine.

Alright I found the p/n for 90mm throttlebody, it's 12580760. However now I have another problem. This tb has 4 bolts whereas the ls1 intake I bought only has 3 i'm told. I also already bought the fuel injector rails for the LS1. Is there anyway that I can use this tb with my LS1 intake. Or at the very least be able to use my ls1 rails and injectors with a ls2 intake manifold?
