Nice to see another F body getting done
Your right it is Top heavy.
It's a Two person job to roll it over on its side or right it at this time but doable.
After I get the Trunk drop offs finished up and the Tail panel back on I will probably remount it to the Bumper mounts, Just for the ease of being able to flip it by myself.
Holding it by the pinch welds I believe is better for the body in my opinion.

I have the bottom all stripped of undercoating now There is actually no other rust any where on the body besides what I am currently working on so that's a good thing no more surprises.
I should be back at it welding soon.

I got a little update Both of my air compressors are pretty much burned up well at least one of them is taking forever to build up pressure. They have been going bad for some time now. Yesterday I finally picked up a Good Pump one that should last me many many years.
I got it used off of Craigs list Its an Ingersoll-Rand 7100 air pump with a Dayton 5 hp motor.
Basic specs:
Air Compressor Pump, Number of Stages 2, Splash Lubricated, 10, 15 HP, 37.0/50.0 Free Air CFM @ Max. Pressure, Max. Pressure 175 psi, Oil Capacity 2-1/2 qt., Number of Cylinders 2, NPT Outlet 1 In., Pump RPM 800, 1100, Rotation CCW, Groove Section B, Groove Quantity 2, Flywheel Included Y, Flywheel Dia. 18 In., Sheave Size @ 1725 RPM 8-23/64 In., 11-23/64 In., Bore Dia. 5-1/2 In., 3 In., Stroke Length 4 In., Cast Iron Construction, Valve Type Finger, Overall Height 25-13/16 In. '

The Motor is way to small for the pump its a Dayton 5 hp single phase It needs a 10-15 hp minimum in my opinion, but it does drive the pump to 150 psi in about 1.5 min from dead empty so it does work! It turns it slow but doesn't waist any time building to good pressure and doesn't struggle when loaded at full pressure either. so I think it will work as is till I get a 10-15hp motor for it.
The Tank is old and too small for my liking it was an up right and been modified into Horizontal its like a 50 gal tank but It was the Pump I was after.
The Pump looks relatively new compared to the Tank and the motor that's being used.
The plumbing on it is all new, From what I gather the Guy had purchased it to build the ultimate compressor for his shop but in the end he ended up just slapping it together on the old Tank and used the Small motor on it he had laying around then selling it for quick cash as he needed money to move. his loss my gain sorta thing.
I will get a Picture up soon.

Sorry for delay But I only work on this thing when I have time.
Work family drinking beer keeps me pretty busy lol

Well when I bought this I didnt have a Tig now I have two I also didn't like Mig welding sheet metal and was a strongly against it now well It has its place.
I like many others am still learning every day and am by no means a body expert or professional restoration expert I am just a home hobbyist at best. with that said let the show begin.
