Trying to keep up lol! As far as the shock mounts, you say "never used for a good reason" is using relocation brackets a bad thing, or just lazy? If i remove the extensions, i dont think i would clear the spring even if i shave the bucket. The rear axle has quite a bit of tilt.
No, i do not know what the gearing is but i imagine it is very low, it seems to handle similar to my 4.9 ford with 4.88 gearing. Where would i find that? Usually I'd look for an axle tag but there are aftermarket covers on the diffs and no tags.
Yes, i believe that IS RTV, the exhaust from that joint back is relatively new.
Do you see a problem with the way that front trac bar is set up? It is still tight so should i be concerned with replacing it since the cheapo-shortcut-damage has already been done?
