Dual or Triple alternator bracket system.

Hey, I'm getting back into the swing of building again after a long period of no fabrication, and I'm trying to find a dual or triple bracket system for a 98 f-150 truck. I suppose I should try a metal shop or something first? Another question I have is when you got to plug in the control module or power wires do you just splice them all? Any information or experience would be helpful.

Thanks
