Energy Suspension Body Mount info

Wanted to put this out there for future reference. I am about half way through the install, just wanted to catalog the additional pieces I needed to buy. 70 C20, note that some mounts are different from the C10. Using the Energy Suspension set:
https://www.rockauto.com/en/moreinfo...031690&jsn=527

Apparently, these kits are made for trucks that don't live in the rust belt. The kit does not include:
Sleeve / washer for the rear cab bushing. In the original, the sleeve is welded to the top washer.
Sleeve for the front cab mount
Bolt and nut for the front cab mount
Bolt and nut for the radiator support mount

Rear cab sleeve:
1.00" outside diameter
0.120" wall
3-7/8". Don't know the factory size, this is what the directions specified. My factory ones were too rusted to determine the original length.
I used a separate washer. 7/16" hole, 3" outside diameter, .120" thick.
This sleeve was a tight fit in the bushing, but I was able to get it in. I beveled the edges a bit to make it easier to get started.

Front cab sleeve:
.875" outside diameter
0.120" wall
2.25" length. This should be about what it was from the factory. Think I measured my factory one at 2.21".
This sleeve fit snug, but wasn't herd to get into place.

Front cab bolt:
9/16"-12, 5.5" long. Use grade 5 or 8.
Locking nut (oval)

Radiator Support Bolt:
This bolt has a square plate on top to hold it in place. I am reusing mine as the rust isn't too bad. The directions specify this as a 3/8" bolt, but mine is 7/16", so I needed to drill out the washers. If I feel motivated enough, I may get new 7/16" bolts, and fender washers. Tack the bolt to the washer and cut the washer down to size to match the previous bolts. I believe I have seen other instructions that use a carriage bolt

Other notes:
I went to https://www.metalsupermarkets.com/metals/ for my sleeves. Only cost me $8.
9/16" is an odd bolt size, so don't expect Home Depot or Lowes to carry it. I got it from a specialty bolt and scew shop.

Hopefully someone down the road will find this information useful.
