Metric coarse thread... Size though? I'm not sure.

The front bolts are bigger than the back.

The Driveline Support Beam's are different for the auto and the stick but the bolts are the same. The rear's are M14x2x205mm. The fronts are M12x1.75x165mm. So says the Parts and Illustration Catalog-a worthwhile $15.00 EBay purchase.

If you mean something else when you say "C-Beam" besides the driveline support beam, sorry, I couldn't find a listing for that part, under that name anyway.

I jacked up my '87 to paint the rear exhaust and spare tire carrier as seen by cars behind you and I fell asleep under the car. Quite comfortable actually. It must be something psychological because the cement floor is normally not that accomodating. And yes, it was BEFORE I started painting, ha.

Scorp, you really ought to buy an Eagle lift. Mine is a godsend, especially with my bad back (Hint, hint!).

Plus my one-car garage w/lift doubles as a giant year-round doghouse, and triples as an effective anti-theft device.

Price is around $2900, but they have sales periodically...My IRS refund paid for mine! (Several years ago) :D
