Ok guys, lets talk ECU's

Getting hard to find the old stuff these days :(
I get it but I have been a buyer of that stuff Just Mopar, but for other makes Ford etc, but have friends that just do that stuff so we trade back and forth alot of parts. stuff for years doing the distributors so alot of it kind of falls into my lap through vendors talking. Just scored a bunch of LFRB of parts I have to go through, mostly 60-70's stuff, Filko, Guarenteed, Shurhit, Mopar etc, out there but you have to hunt for it. Then you have to figure out what it fits. Hell I have to have 50 old ignition catalogs. Then of course I get other makes in for Ford, GM etc. I trade them with guys that just specialize in that stuff.
