Still can't imagine why you'd go to market with a lousy system that's not very common in wrecking yards (Dodge truck/van '88-'91 only) versus a much better system that's common as dirt in wrecking yards (GM).
well since I have a chrysler only yard at my fingertips (less then 10 miles away) and everything is priced very reasonably since I am friends with the owner (you couln't buy GM for my prices) and each time he gets a TBI truck in or something of interest he lets me know and lets me have first dibs on parts
some people prefer dodge parts, I'm not against creating a GM TBI kit but frankly I can't get GM parts at reasonable prices around here. With the M body the GM style TBI wouldn't have fit since the GM TBI unit is physically taller I have just enough room for a modified breather stud (original was too tall) and a 4 BBl air cleaner and maybe if I'm lucky 1/4" to spare
I don't know how a GM TBI unit would fit in an early A if a mopar one is tight in an M body
