1970 C-10 / 1998 Yukon hybrid
Hey guys, I'm new to the forum. I've been searching C-10 stuff for weeks and I kept landing on this forum. I thought I'd share some pics from my C-10 project I just started. My plan is to put a rat rod style C-10 body on a 4X4 Yukon frame retaining all the factory options except the air bags. I'm thinking I'll go with 20" wheels but I'm waiting on that until I get the body situated on the frame so I can get the offset correct. I'm planning on using the floorpan and firewall from the Yukon since the mounts will bolt right onto the frame. Also the steering column and HVAC components will bolt right in, I hope...

Re: 1970 C-10 / 1998 Yukon hybrid
I suppose most will cringe at what is basically a re-bodied Yukon, but I kinda dig it. Dang sure will be more fun than driving that Yukon.
What is the distance from the firewall of the Yukon to the front axle centerline? Any difference from the C10? Just curious if that is gonna put the back of the drivers seat out past the back wall of the cab in order to keep the front wheel centered in the wheelwell? Those Yukons had so much more leg room. From one guy not afraid of a sazall to another, carry on. ![]()

Re: 1970 C-10 / 1998 Yukon hybrid
Please keep us updated. I saw a similar project several years ago, where a guy took a newer truck and kept the newer firewall and dash and mated a 67-72 body to it. It looked pretty nice. I've searched, but I can't find it anywhere.
Good luck on your build. It should be very interesting. |

This is very similar to what I am wanting to do, just with a 2000+ Tahoe or Yukon. Keep us updated on progress!

Re: 1970 C-10 / 1998 Yukon hybrid
Thanks for the input guys. I started fitting the floor/firewall last night and the firewall is forward about 4 inches. This may not be a bad thing though because I was worried that my steering column was gonna be too long. I plan on test fitting the column tonight to see if I should try to move the firewall back or just fill in the gap with sheet metal. The airbox intake is gonna be tricky as the stock air intake setup is completely different. I may try to incorporate more of the Yukon air box/ intake components. Cooper, I think my seat is gonna be fine. The front outer bolt holes even line up for the stock bench seat! I'll attach a pic of the pan. As for cringeworthy crossovers, here's my last project.

Re: 1970 C-10 / 1998 Yukon hybrid
So if I'm reading this correctly if you fill the gap from the firewall you will have an extra 4" of leg room? If so, that is perfect. Our trucks aren't the roomiest vehicles and 4" more would be amazing.

Re: 1970 C-10 / 1998 Yukon hybrid
Sorry about the million questions but is the pic with the cab on the frame at the ride height you're going for (I hope so, it looks great) and have you lowered the suspension at all? One last question, what size tires are you running?

Re: 1970 C-10 / 1998 Yukon hybrid
Actually the current ride height is not unobtainable. I set the frame down on the bump stops just to get a starting point. I figure it'll end up 2 or 3 inches higher. I plan on running 20" wheels so that should help keep the same stance. It has the stock 17" wheels on it now with some tires I grabbed out of a local tire shop's junk pile just to roll around the shop on. 230\50-17 on the front I think and I can't remember on the back. As for the legroom, yeah, easier said than done but my plan is to extend the cowl out the extra distance to meet the late model firewall and hopefully that'll mean more legroom and room for the heat/air unit under the dash.

Re: 1970 C-10 / 1998 Yukon hybrid
How close is a standard shortbed to fitting right on? I know that the tahoe you used is the same chassis as a regular cab shortbed of the same vintage

Re: 1970 C-10 / 1998 Yukon hybrid
I didn't realize that the chassis was the same as that year SWB, thanks for the info. If the numbers I found are correct the wheelbase is 2.5 inches longer than the C-10 SWB. My body is a LWB so I was already planning to shorten my bed anyway. I figure a few extra inches of bed won't hurt anything and may even look better. I'm also planning to incorporate the Yukon gas door setup into bedside behind the left rear wheel.

Re: 1970 C-10 / 1998 Yukon hybrid
Cool build, Here is a similar project that has not been finished. Might get some ideas from this guy.
http://67-72chevytrucks.com/vboard/s...d.php?t=498570 He went from a 2wd to a 4wd but it looks like yours is quite low, you did say in the first post that it is a 4x4 Tahoe so is this staying 4x? kind of confused me there. I have to ask the dumb question on the Porsche.. How does the trans drive the rear wheels if the drivetrain is in backwards? Or is it front wheel drive? You clearly have some fine skill so I am sure this will be a clean conversion. Keep up the good work. ![]()

Re: 1970 C-10 / 1998 Yukon hybrid
Thanks! The Porsche is a AWD car from the factory. It has all the stock drivetrain with a adapter plate to bolt the engine to the transaxle. Imagine a VW bug transaxle with a torque tube coming out of the front going to a front final drive unit. Here's a link to my build on it.

Re: 1970 C-10 / 1998 Yukon hybrid
67c10, My truck will retain the 4X4. It has the push button setup and I'll be using the Yukon harness and all the electrics right down to the auto light sensing rear view mirror with the built in compass. 4X4 will not be for offroading obviously, more for towing and maybe icy conditions and the like.

Re: 1970 C-10 / 1998 Yukon hybrid
I got the cab situated on the floorpan and spot welded in place. I got the bracket the brake pedal and steering column mount to fitted last night. Looks like I will have room for the Yukon gauge cluster in the dash too. Here's a couple of pics of that and of where the firewall sits in relation to the stock C-10 firewall.

Nice, that won't be that bad to fill the gap.

Re: 1970 C-10 / 1998 Yukon hybrid
Does anyone know the thread size and pitch on the fender bolts that go into the cowl? I'm guessing 5/16X20? I'm not that good with standard bolts and I have almost none in my shop to try.

Re: 1970 C-10 / 1998 Yukon hybrid
Thanks Mark! I'm really excited about the truck. I had a 70' when I was in high school in 1989 and it's bringing back some good memories.
