Wow, 7 of your last 8 posts are "I like pizza". Real helpful... :dunce:
Here's a pic of the tranny mount out of a '99 with a 242 and an AW4. It has 4 mounting bolts, offset to the drivers side.
And here's a picture of it in place looking from under the driver's door. Mine has been slightly modified and has a 1/2" spacer underneath it.
Most will say that using poly for the tranny mount will transmit a lot of vibes to the unibody. The OEM is usually the recommended replacement for a good mix of durability and ride quality.
Looks like the difference in the heights is based upon the location of your exhaust bracket. Check out the install notes listed on the Quadratec website to figure out which one you need. Hope that helps.
