When you get it jacked up and some jack stands under it, do you know where the motor and transmission VIN pads are? Both are on the passenger side. The one for the motor is on the bottom right edge of the block, next to the block drain plug. Look in the lost and found section here, and there are pics showing what it looks like. The pad on the 4 spd with the number is a raised up place on the same side, with a flat surface. Scrape the crud off of it to be able to read the numbers. The numbers on those pads should say 2B5?4889
