Supra - I have replaced my evaporator core (due to a leak), mine's a 1988 B2200.
Guess what - I bought my evaporator core from AC Kits (actually, their walk in service and parts store here in town is AMA Auto Refrigeration), this was back in 2002, still using it, works great.
I went on ACkits.com and looked at the parts listing for the 1988 B2200 and the 1992 B2600i, and the evaporator parts shown are all exactly the same. So which evaporator did you order/get? The 27-33198 they call a plate/fin type which doesn't look at all like mine. They also list a 27-33650 which they call a copper tube and fin type. Mine is copper and brass tube type, assume it's the second number, but I think I might have that number written down at home.
Back then they only had the copper/brass one available, and the dealer one was 2X the price and special order, this was in stock across town. I see they also now sell a complete evaporator core/evaporator case assembly as a unit (27-33650), that would include the expansion valve inside, I may have gone that route for simplicity had it been offered then.
Did AMA say they had two different types available? Did you talk to TRB or Jack when you called? 602-233-0090.
Installation including evacuating and recharging with R-12 took a full morning; my 11 year old daughter and I.
