Well looks like springs and shocks will have to wait a tad bit longer. I knew right away that I was going to be dealing with some issues on the engine skid. When sold to me the OEM skid was not installed but was provided sans hardware which I thought might just be on the frame. Two weeks later I go and look and realize I don't have the hardware so I had up to groove and grab some. Try to install the skid only to realize that I had a diff drop that gets in the way. In the process though I also realized that the frame thread were not in the greatest shape. They were a wee bit rusty from being exposed.
Fast forward to today and knowing this I tried to take the Toyota hardware and some pb blaster to clean up the threads. Second hole made me realize how bad the threads were when the bolt got pretty badly stripped. So I had to pop down to Lowes and grab a M8 1.25 tap. Spent about an hour cleaning up threads very slowly. Most holes I had to tap about halfway and then clean the tap. Last hole I knew would be bad as it had a ton of road grime in it which I could only clean out so well. Took my time on him and sure enough it didn't look good afterwards. The inner parts of the threads were not sharp which made me suspect a PO had already stripped it.
Anyways finally get to the actual installing and everything goes pretty smooth (floor jack really helped with this job). Torque up from back to front. Couldn't get a wrench on the passenger trans skid nut though, it has almost no clearance between it and the cat so I had to give it as much gutentite as I could with a ratcheting box wrench. Get to the front skid though and torque goes well on all but two bolts which felt like they just stopped tightening around 25ish ft lbs. One of them of course was that problem hole. I only needed 28 on them though so decided to just leave them as is before I strip them completely. If they don't stay I might have to drill and tap them in a tad bigger size.
All in all though I'm super happy I've now got armor. Also took a buttload of pics that I will send to RCI that hopefully will be useful for them to make a guide on 3rd gens which they don't have yet.
