55.2-59 A few one off questions

[FAKKY]

1) anyone got reassembly thread with good details of front end sheetmetal. I dont remember what sizes the bolts for say radiator support are and they sont seem standard. Also stuff like where to put those clips.

2) currently just got 8.8 rearend in. Wasnt going to flip it to lower. How much clearance do I need between frame and axle to run ok in this stock configuration without bottoming out.

3) will be starting wiring soon. Never done before. Who has a good overview of where grounds are needed. Central grounding distributor or block better ? .
Grounds for engine (ls) starter ..ac...fuel tank ...etc

4) wiring also .... anyone using a breaker for main power feed ?
