Just thought I'd share a resource. Found a shop in Wall NJ called Mike's performance that carries Amsol and Redline products. They stock 75w90, will now carry MT-85 (thanks to your's truly) and will order any other stuff with a 1 day shipping time. Prices are very competitive... think the MT-85 and 75w90 was 12 a qt and the 5w30 Reline (not stocked but available with a days notice) was 10.
Amsol was also 10 for 5w30 (and in stock).
Guy was very nice, didn't require a deposit or prepayment for the transmission oil. Personally it is worth it to me to pay a dollar more a quart (if that) in order to be able to pick it up in person.
Figured I'd give him a shout. Check out his site below for contact/directions.
