Need the correct FAST rail MOUNTS. (LSXr102) Apparently I ordered the wrong damn kit... 
..... It was on sale whaddya want.......
How much of a difference is there between the LS1 rails and the LS3 rails? I know the mounts/brackets are way off, but is there any difference between the injector mounting depth into the rails?? These sit kinda shallow on the top of my injectors. Is that normal? I mean, the o-ring sits in there completely, but feels a little shallow to me.
Where can I get the correct brackets without having to re-buy the whole damn kit? (For the LS1 102 intake) Wonder if Jon @ FIC would be willing to trade me.........again.......

^ I'm not fabing anything that will risk catching my car on fire. There is a correct setup for this and I am going to run it. No more short cuts with a fuel system.

The injector hole and spacing is very simmilar but the FAST 102 rail is very different mounting from all the rest. We have specific 102 rails for all injector sizes. In fact we have rails to fit all intake manifolds with any injector. If we don't send in your manifold we will make it.

^ Wish I would have found that response yesterday. Just sold mine. Ah well.
There was a P/N discrepancy. I got it.. 146032 is the CORRECT P/N for the LS1 LSXr fuel rail kit. Thunder Racing is listing 146027 under 98-2002 F-Body > Fuel System > Fuel Rails. Just called and got it straightened out.
I'm running 42# stock injectors (Same body, different bottoms.)
The spacing was just way off = was the wrong kit. Easy-peasy. TR just has to order the correct kit (and I hope they fix their site and listing as to avoid any future headaches.)
