Again, thanks! | | | | Joined: Jul 2011 Posts: 22 New Guy | | New Guy Joined: Jul 2011 Posts: 22 | I have these strange looking screw heads all over my 1950 Chevy and not sure what kind of tool to use with them. Looks almost like a socket/Allen head but not a hex shape. Looks like a rectangle with rounded sides. The truck I have was an old Air Force vehicle and I'm wondering if maybe that was a special tool. Any suggestions?

If you look in the tool forum it has been discussed along with sources to buy the tools.

They do require the proper tools to remove/install them, but they're not too hard to find. Try Napa or contact your local Snap-On/Mac/Matco dealer.

I guess the rounded rectangle I thought it was was the post-rusted clutch head!! Details are a little harder to see  I'll look into getting a bit set this week. Will make my life a whole lot easier. Thanks! | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Kim if I can give you a tip that I've learned from taking apart several of these old truck with rusted fasteners. If the old man doesn't have one of those new 18v impact drivers that use the 1/4" hex shanks, get him one for his birthday so you can use it to take out those rusted screws and bolts. With a little PB Blaster or Kroil they work magic on old rusty fasteners. The ones that won't come loose it will shear right off. You can get tons of bits for them and there are several Ebay sellers that stock clutch head bits with a hex drive. Here's a picture of the drill mate that came with the driver, it looks almost the same as the drill. http://www.pbase.com/dennygraham/image/136174550 Denny Graham Sandwich, IL

My passenger side door was hanging on by one stubborn bolt and using the gun, it seemed to come loose with very little effort. Great tool! For now, I'm borrowing theirs, but I'm sure that as I move further along with this project I'm going to start acquiring my own tools. I'm not a purse and shoes kind of girl  I'll take a man with tools instead LOL | | |
