Finally got the factory rear seat installed. I moved it up about 6" from the factory location and now I can lay a 35" spare between the rear seat and close the tailgate. I still have no idea why the factory location was like dead center of the bed. The top picture is the stock location and bottom pic with it moved up, I don't think anyone would even notice.

Next up is some more metal work on the inside and then mount the factory front seats!

That's what the cool kids do..... :waytogo:

I moved mine up a few inches as well to accommodate the rear struts coming up through the floor directly above the axle.
It was either move the seat forward, or lose it completely. Seemed like an obvious decision.

You can’t hardly tell it moved. Did you also move the crossmembers under the body? Or just use bolts and washers to bolt it to the body in the new location.
 
I had a hard time telling you moved it. Makes sense though when I think about it.

Yep, moved the rear seat cross-member right up to the floor cross-member. I'm also going to weld the 4 plates on the top in the new location as well.
From the side you wouldn't even notice that it was moved but it makes a big difference in the space behind the seat.
 
Mine only has two brackets. The other two holes are for the center seat belts

curious, the 72’s don’t have 4 brackets on the back of the seats or you just didn’t install them back?

From what I can tell, early production year in 72 they went to 2 brackets and carried that through going forward.
 
Need exhaust ideas... currently running a 1991 350 TBI with stock manifolds with dual exhaust, think they may be less than 2" diameter?

What diameter and brand of mufflers should I run? Want it somewhat quiet but not to quiet as it is full convertible with no noise insulation, basically an empty beer can on 35"s so would like to hear myself think while driving.

At some point will swap to a 6.0 LS so maybe an exhaust that will sound good with that combo as well?
 
Slightly different truck but this guy is running long tubes with no cats and just put the magnaflow 12092 muffler on it. It's quiet for sure. I just ordered it for the wife's Silverado with long tubes and high flow cats. It's a 3.5" but they make them in smaller sizes. I'm useless for quiet as the blazer has long tubes and no cats and bullet mufflers and the charger has long tubes with high flows and borla atak.

 
That sounds good!
 
3" single sounds good IMO. IIRC the OG UAV was 350 TBI with 3" single wasn't it?

Yeah, but it had a cat. I don't want to go from duel with no cat to single exhaust.
 
I get that...

For a stockish 350 dual 2.5" is never a bad choice. Enough good sounds without being stupid, and routing with 2.5" is still easy enough. That old skool 2" dual is terrible, so no matter what you do it's gonna be a big improvement IMO.
 
Single 3" will move A LOT of air, concern always seems to be the layout-Y pipe malfeasance at the front driveshaft area

For that reason I went dual 2.5"
It's not holding up the SBC any

I like the Thrush welded. They aren't that quiet, and its certainly louder than the Magna @mrk5 has
But it's like mouse whisper quiet

Yeah, I remember messing with the y-pipe and driveshaft clearance on the 90.
