Awright!!!--Had to go all over town this morning on business, so thought,"What the Heck---I'll stop at the Chevy dealer and see what their flat rate is to replace a rear main seal in a chevy smallblock."---Can you believe $407.55! That includes a new rear seal and a pan gasket.--but $300 of the cost is labour. I guess I'll be spending some time laying on the concrete floor under my roadster pickup.
