Coldshot; I use 71 Camaro motor mounts now. (cheaper), and build my pedestals out of tube steel and 3/16th uprights. And yes. get your cab mounted up before you mount your driveline. You need an inch of clearance from the firewall. That is to give you maximum clearance for your e-fan up front.

Bauto52; my best advice is that either route requires lots of research, careful measurements, and some mechanical aptitude to accomplish. In the end, it's a matter of preference. Some will tell you that S10 swaps are a "hack job", but if they are done correctly, they are very roadworthy and safe. It is important on either MII or S10 swap, not to cut corners. Nothing is more frightening than an unsafe vehicle!

User Error; The one on the passenger head should be between the second and third exhaust port. You can use that one, that is the "non ecm" sensor. That is used for the gauge. The drivers side should be between the 1st and 2nd exhaust port. Identified by a plug. Pull the plug and insert your new coolant probe or aftermarket sensor.

Coldshot: sandblasting may work, but likely it will work the wax farther into the pores. I always use the Muriatic acid.

Fod's Garage; You are correct. on 47-50 the rear stand should be 3/4" taller than the front. For 51-54, it should be 1/4" taller.

Californiadaddy; You need S10 V8 conversion headers. The ones you posted look to be correct, but be sure the drivers side header has the center 2 tubes sticking out. The steering shaft will have to go through those two tubes to the column. The headers should like like picture 2.
