Hi Rafa, I was referred to you by Chris (slosurfer) who said you were a good parts guy for these vans. I've got a week to tackle some repairs and was hoping to order some parts from you. I can come pick them up, live not far from northridge. I don't know the part numbers, but here's what I need:
first, it's an 89LE 4WD and am planning on replacing:

water pump and gasket (think part # is 16100-79035 or 79036, not sure the difference & 16124-71010
valve cover gasket
t-stat and gasket
pcv valve and hose
and coolant

thanks and I look forward to hearing from you soon!
