Thx guys for all the comments

and Brett, always appreciate the precise attention to detail.
Aeromotive rails ship w tall and short mounting brackets. Comp Preformance (Fast 65lb injectors) could not tell me if I needed the injector extension collars or not to clear on a factory intake w the Aero rails, so I bought them just in case. I'm pretty sure if I go w a FAST 102 in the future they'll come in handy, but the Aeromotive rails will probably be useless.
Betcha Gregg knows the answer to that...
