I just placed an order with the site Dan referenced above. The parts were for oil level sensor replacement which were quite small with exception of the lower pan gasket. Shipping came up as $65.00 but a quick call to an employee named Gabrial got the shipping lowered to $20.00 once he knew the size of things.
Thank you, Gerry, for the writeup with part numbers. I'll report back when I receive the parts.
