Thanks Steve.
Great information and encouraging .
I brought the SD7H15 Sanden which is quite probably the slightly larger unit you purchased. Was going to flush it with the r12 mineral oil and reuse R12. I did buy the new three speed fan unit from Halls but when I went to put the dash in it was simply easier to drop the old fan unit back in . The wiring threw me because I did not get it was a three speed not a two speed. Those crazy Mexicans ! Also the cable vent controls looked like they needed some work to fit them . Another future rainy weekend job I think !
The hose ends are slightly short to the compressor ( boy -what fun it was getting them back through the side channel ) and the fit under the dash is something else , as 6997 is a factory RHD.
The hoses and pedals are in a long term ,permanent and intimate relationship.
The charge ports will have to be installed on the hoses. so that will be a good way to close the gap to the compressor .
Both the original York compressor , fittings and all associated hardware are FUBAR big time ! ( 30 years in a slightly moist box can do that to you...!) . Even a mustang guy wouldn't want them unless he has a boat.
The rear fan unit looks OK , new dryer unit is ready to go . Getting closer !
