1972 Buick Skylark

Is it missing an air dam under the radiator to help the air go up through it instead of under it? That can cause them to run hot at highway speeds too.
 
Get that one rodded out. If you can find a radiator shop.

Glad it's running and Patrick is enjoying. Sounded good what I could hear.
Great job Dad
Thank you! The only radiator shop we had around here closed up a couple of years ago and that guy wasn't super reliable; he just stayed in business because he was the only show in town.

I know the GS models had a front spoiler deal, but I don't think the base models did.

I do have a couple newer fan clutches I was thinking about swapping in just to see if it has any affect.
 
Like their father, my sons are nerds. Patrick talked his older brother into driving the Buick to their weekly Dungeon & Dragons game.


Big brother drives a 2000 Tundra, you can tell in the video he's not used to old car power steering.
 
was that the power steering making that noise ?
Yeah, he hasn't learned not to jam the wheel against the stop.

We still need to get the new package tray done, but we put the rear seat in so they could give a ride to someone if needed.

It's just a $35 seat cover from Amazon, but it fit well. Being able to remove the seat in 2 pieces really helps make the install better.
 
I'd like to get new replacements for some screws we removed. They have 3/8" hex heads. Diameter is 1/4" or real close.

Are these #12 sheet metal screws, or something special for automotive? The one flat phillips head in the picture is a non-factory replacement.
 
If you want a 455, and transmission, this guy has one. Tom Priddy 970-964-5563. $700 for both. Its here in Montrose.
 
Haha, the 350 is good enough for this kid. I want him to be the instigator if it's getting a big block. I'm interested to see if he gravitates that way or is happy to keep it how it is.
 
Those screws look like Tek screws, not something GM used.
The 2 screws with X's thru them I'm 90% certain are substitutes. The one is a phillips and the other required a 10mm socket.

GM used plenty of the 3/8 hex sheet metal screw 5/16 hex and 1/4 as well now they are 10mm and 8mm 5.5mm

I have buckets full of them. They look the same as the screws used to hold stuff to the firewall (ground strap, heater box, etc) on squarebody trucks. Typically, 7/16 hex for the head in the 70s and 10mm hex in the 80s.
 
Now I'm questioning if I used 7/16" or 3/8" socket. Can I get these at the hardware store?

There are also some with a 3/8" hex. Those started getting replaced with 10 mm around 1975 from what I have seen.
 
7/16 hex tend to be core support attached items, grounds, heater box to firewall.

3/8 hex can found in similar places but more so in the passenger area.
Only a concourse car really matters.
Thou I like to use oem fasteners when possible. Having them match too. I get it.
 
Those particular bolts thread into u-nuts so I need them to match. I'm hoping I can just get them from the hardware store. Don't want to pay for shipping to get $12 OE type bolts from one of the parts companies.
