For helping keep this great

on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: May 2013 Posts: 20 New Guy | | New Guy Joined: May 2013 Posts: 20 | My legs are really long (38" inseam)and I need to make more leg room in my '51 AD to make it safe for me to drive. As it is I have to angle my knee to the right to keep it from colliding painfully with the steering wheel and pushing on the brake pedal at an angle causes my foot to sometimes slip off. NOT good. I considered extending the cab ala club cab but have decided that I lack the skill needed to pull it off. I checked with a couple body shops here and they both wanted a fortune to do the work.(fortunes are really scarce these days). I will be moving the gas tank to under the bed which will gain me an inch or so which means I only need about 4" more. I'm considering moving the steering column cut out in the dash higher (closer to the instrument clusters)to give a more vertical column, using the column from my S-10 doner and mounting it higher up to gain some more room. The 13" steering wheel should help as well. If all else fails to get me the necessary leg room I will move the firewall (at least on the drivers side) forward a few inches. I'll be powering the truck with a V6 (either Buick or Chevy) and keep it as far forward as possible to give me the room. I'll be using an automatic trans so no problem with clutch linkage. The master cylinder will also be changed to a firewall mounted unit. Has anyone ever extended a firewall? Comments please, even if you think my idea is the dumbest thing you've ever heard of in your whole life. Other ideas. If you have any other ideas to gain more leg room please post them here. Thanks, Cliff

I especially like the firewall concept, mostly 'cause it's thinking out of the box  | | | | | Joined: Dec 2000 Posts: 3,399 Gas Pumper | | Gas Pumper Joined: Dec 2000 Posts: 3,399 | Surgery to shorten your legs would be cheaper. LOL! J/K | | | | | Joined: May 2013 Posts: 20 New Guy | | New Guy Joined: May 2013 Posts: 20 | red58 Thanks. Fixed it. DennisM Good idea. Will have to see if the S-10 seat will fit. Deve Great idea. Shorten legs, remove some vertebrea, would make buying clothes a lot easier a cheaper too. Sadly Medicare won't cover it. I don't know when I will get to this. Since retiring my honey-do list has expanded exponentially. I will keep posting here as progress advances.

It will fit but it's not what you want. The S-10 seat is much too narrow for your cab. The ideal seat is a bench or split bench from a full-size GM truck. 88-98 works great, but newer may work as well (you'll need to measure). My dad's '52 has a bench seat from an 88-98, and it fits great, is comfortable, and I fit very well in it. I'm smaller than you at 6'2", but this is your best bet... Try to keep the floor as flat as possible, that makes a huge difference. | | | | | Joined: Mar 2008 Posts: 1,775 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 1,775 | I've been condidering the extended cab thing too. The best method would to be find a panel truck body and graft the rear of your cab to it. I don't have the skill set, either. I'm not afraid of cutting and welding, it's the end result I'm worried about. I may end up with garbage for a cab. Have you also considered adjusting the pedal throw? It looks plausible to modify the brake and clutch pedal assembly so you don't have to lift your leg to your chin. About moving the firewall, I did see a link awhile back where someon extended the cowell area for more leg room, I'll do some digging to see if I can find it. Here's some eye candy in the meantime https://48chevy.shutterfly.com/

But thats what i love about these trucks is that they basically stuck "couches" in them. I think with modifying the back cushion, or closing the angle on the seat frame, so its closer to 90 deg? | | | | | Joined: Oct 2007 Posts: 725 Shop Shark | | Shop Shark Joined: Oct 2007 Posts: 725 | This may sound a bit crazy, many things I say do, but why not cut out the of the floor where the pedals go through to the frame and move the cab back? I know there would be problems, but could it be any worse than extending the other end?
Just my 2 cents!

46gmcpu Thanks, I will look for one of those.
Whiedog / bartmos I will be using a hanging brake pedal (the only pedal since I'm going to be using an auto trans) I will have to be careful not to shorten the throw too much and have it bottom out on a hard brake application. The only way I would cut up a panel or suburban body (assuming I could find one) would be if the rear of the body was trashed.
bartamos I will see if I can find one of those tilt/tele columns.

I have also had a love of the wood bodied trucks of the 20s and 30s since adolecence. Check out the peanut/popcorn truck pics I found. I could build something similar minus the roasters and popper. My woodworking skills are quite a bit better than my sheet metal skills. here are the links.
