Tricks to get more leg room? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

MrC1 · 10-08-2005, 11:48 AM

I'm going to replace the factory bench seat in my truck, but while I'm at it, I'd like to get some more leg room (I'm 6'4"). I was thinking of somehow making the back of the seat about 1/2 as thick as original. This would also provide extra leg support 'cuase my butt would be further back i the seat.

Any thoughts on this? Anyone done something similar?

I used a seat out of a 91 Chev P/U. It is the 40/60. I took out about 2 1/2" on the brackets. That made it set lower and gave me more head room. The narrower back also helped a bit in the leg room area.

Bill72BB · 10-08-2005, 01:00 PM

FYI : I have the 98 Chevy 60/40 wont work for you unless you take out the tank.

ebfabman · 10-08-2005, 02:09 PM

a) move the tank to the back.

b) trim the sheetmetal under the back glass to give more room to move the seat closer to the back of the cab, depending on your choice of seat.

Thought I remember a member who moved the steering wheel forward.. how ya do that??

MrC1 · 10-08-2005, 03:21 PM

I'd like to move the tank to the rear for sure, but that's a project down the road I think. Still not sure how to run the filler neck since I don't want it in the bed. Probably something out the rear by the bumper I'm thinkin. Anyway...

I was thinking, in the meantime, since the factory seat back is angled, I could just remove some thickness towards the top of the seat, allowing it to be slid backwards a couple of inches. Sound feasible?

HeavyD · 10-08-2005, 04:02 PM

IIRC if you collapse the intermediate shaft that connects the steering column to the st. box, you can make the steering wheel/column go in toward the dash a little farther.

68Stepbed · 10-08-2005, 05:49 PM

I'm 6'4", 300 and I have decent room with my 92 bench. I could use more room, but I have plenty to drive comfortably.

ChevLoRay · 10-08-2005, 06:58 PM

They's a feller in Texas, what took and added 6-inches to the length of the cab of his silver '69. You may have seen it in the magazines. It's slick. I know doing this is at the extreme end of the spectrum of making room in the cab, but he has one nice truck.

I, too, wonder about a shorter steering column. My problem isn't my height, unless you consider that I'm too short for my weight!! Not quite horizontally challenged, but gettin' there, one day at a time.

Jeff M. · 10-08-2005, 07:08 PM

Oh yeah, I also moved my steering column forward. I relocated the neutral safety switch up about 2" and collasped the link in the steering shaft a tad more. I had to weld on a little tang on the inner steering column tube for the neutral safety switch along with cutting out for the switch and drilling the new mounting bolt holes.

jd4300fel · 10-09-2005, 11:01 AM

not to high jack this thread, I am also in the plus 6 foot club, My question is to ebfabman. do you have any more details on your sugestion?

ebfabman · 10-09-2005, 01:54 PM

Yes I'm 5'11 but I have a 35 inch inseem. Seems like no matter what kind of vehicle I get into, there is never enough leg room.

If you remove the seat and gas tank from the cab, this is what you have. If you remove the area outlined in red you will have close to a couple more inches to move the seat back (please excuse my sloppy drawing)

5150 · 10-09-2005, 02:27 PM

Go to this link and it will tell you how to collapse the steering shaft. It's really easy, especially if I can do it. I haven't installed the neutral safety switch yet.

Here's a pic of mine done. I also have the 99 and newer buckets. You should have even more room.

Did you have to remove the fuel tank to use those seats?

Blue85 · 10-09-2005, 03:23 PM

Ebfabman, Do you have any pics of the finished job after cuttin that piece out?

ebfabman · 10-09-2005, 04:41 PM

Yes, but I'll have to locate them. I'll try to find them and post them maybe tomorrow....ok?

SCOTI · 10-09-2005, 05:47 PM

I too am only 5"11" but seem to have longer than normal legs. Several months ago I did the method Efabman suggested in his post on a spare cab I have (but only on the drivers side) & it definitely made a difference. I don't understand how moving the steering column forward benefits legroom. I first tried moving the extra column I had forward as far as it would go toward the dash after reading that some guys tried that method. It didn't seem to make that much difference. Granted it was just mocked into place w/a jackstand & some wood in the engine compartment, but it seemed as though the steering wheel was in too close of proximity to my knees if in any position other than straight (which kind of defeats the purpose of a tilt column).

After notching the rear wall, that made a significant difference. I can put the seat where the stock bench would be positioned & recline back several positions or I can recline the seat back 1 notch & move it farther back on the tracks enough that I might be too far from the pedals for comfortable driving.

I based my measurements from the roof to the center of the bottom seat cushion & from the lower edge of the dash to the center of the top cushion (back rest). I set my bucket seat up 1" lower than a stock bench & approx 2" farther back. 2" doesn't sound like much but it sure feels like it.

Blue85 · 10-09-2005, 08:18 PM

thanx a lot man

No I had to redrill new holes and reinforce underneath the floor pan.
