I just recently acquired a ‘77 C20 Scottsdale. I’m wondering if ethanol free fuel is the way to go?  Am I wrong in thinking it’s less important beginnjng jn the late 70’s?  Excuse my ignorance, please. . This will be primarily a 3 season driver. I’m refueling every 2-3 weeks presently with the amount of driving I’m doing in the truck. Probably will not drive it much in the winter, here in Montana, except for during our brief warm spells when there’s no ice.
Any advice, thoughts on fuel differences is greatly appreciated. Thanks in advance.

How to set the height of the front of your seats if you put 1991 suburban seats and console in your 70s C20 with a small hump  Got to get the front center floor brackets out of the suburban with the seats and console.

Had to bend the rear of the tracks upwards to fit the upward angle of the pickups floor, suburbans have flat floors.  bent them up, bolted them down but the front of the seat is way too low.

This is how I decided how high to make the front of the seats.  I used long bolts with nuts as spacers.  keep trying different amounts of nuts to space it higher or lower.  I'm 6'2" so this is what worked for me.  Once you've driven it a while and its comfortable, make the permanent brackets in the shape of the originals but taller.  There ya go.

Also notice on the console how I spaced it up higher for the pickup trucks floor vs the suburban it came out of.  everything will be leaned way down in the front.  lift all the fronts as much as you like to make the console level and the seats comfortable, so it supports you and your hips don't feel like disintegrating after 50 miles.  Seats leaned too far forward are pure torture.

1st pic is console set like i wanted it using long bolts and a piece of pipe/tubing to set the height and then using nuts as spacers to decide the final height of the seat front.  you can see the super short brackets above the nut spacers.  I copied that bracket just made it taller.  seat sits a few inches taller than the bench seat so no more feeling like your butts dragging the ground...  its more like sitting in a chair which is helpful for tall people.  8)

2nd and 3rd pic is the finished brackets at the height the bolts set for me.

4th pic is how they look from the top seats vs console level

5th pic after raising the console I was able to hide the amplifier underneath it.

Hello all. Newbie here. Just recently picked up a ‘77 C20 Scottsdale. I completely underestimated how much I’d fall in love with this thing.
It’s got some surface rust that appears to be superficial. I’d like to keep it that way. It’s got a great look and I’m not interested at this time in painting. What are you guys doing to prevent progression and keep this surface stuff in check?

I bought a 4L65e transmission from monster transmission back in 2018 before I knew about their poor reviews and it came with a Thor torque converter that I paid extra to support over 500hp.  Does anyone know why this bolt ring would be welded on to it and what purpose it serves?
