body mount bolt replacement day 2

With my hardware in hand I assemble the mounts on the passenger side. First mount ISSUE!
The new longer bolt I purchased won't work as the threads are not high enough on the bolt and I bottom out the but long before I get to 50 ft lbs. If you look at the first picture you can see the difference in thread length. Fortunately the old bolts are in pretty good shape so I cleaned them up and reused them. (I will make a post of just the hardware list). All the rest go well with the exception of the back two on the passenger side. They were pulled down tight before disassembly but now they have a gap. The worst being 5/16". Now I get to make some spacers. The third mount on that side was tweaked and I persuaded it back into shape and that may have caused some of this gap. Finished the day sanding the hood and applying Rustmort. And wondering where will I ever find a NOS hood ornament. The last photo is all the wasted old mounts. The cool part is all the parts that are black from the Por15 spray episode.

Thank you sir.

Here is the hardware list from the WMB. Your results may vary.
Front mount: Times two
Bolt is 9/16"-12 x 6" with 2" of threaded area. I included the tapered area in the 2" measurement.
Under the head of the bolt in the cab was a flat washer 19/32" ID 1" OD 1/8" thick.
Under the body on top of the upper bushing was a flat washer 3 3/8" OD 5/8" ID 1/4" thick
On the bottom of the lower bushing next to the nut a flat washer 2 3/4" OD 5/8" ID 3/16" thick
2nd mount: Times two
Bolt is 3/8"-16 x 4" carriage head with 1 1/8" of threads.
Under the body on top of the upper bushing a flat washer 2 3/8" OD 1/2" ID 3/16" thick.
On the bottom of the lower bushing next to the nut a flat washer 1 7/8" OD 1/2" ID 1/8" thick.
This size is used on all the rest of the body mounts I will call it the Bottom flat. (8 total)
3rd mount: Times two
Bolt is 3/8"-16 x 2 1/2" hex head with 1 1/8" of threads. With the Bottom flat.
4th mount: Times two
Bolt is 3/8"-16 x 5 1/4" carriage head with what I believe to be 1 1/8" of threads. The bolts are so wasted I can't be 100% sure. With the Bottom flat.
5th mount: Times two
Bolt is 3/8"-16 x 6" carriage head again not certain but believe 1 1/8" of threads. With the Bottom flat.
I used Nyloc nuts for all the mounts.

Just to make the list complete here is the core support bolts. Times two.
7/16-14 x 2 1/2" carriage head with 1 3/4" of threads. I didn't measure any of the rest of the core support hardware as it is easy and cheap to get.
Photo from end of day one showing the old and the new. I would have more photos, but apparently the camera ran out of room, or space, or film, or something like that.
