Now I have to align all my front sheet metal so I can mount the core support to the frame.
I will post a picture of the dash I had my Uncle machine out Later. It was made to look like the original dash panel but we are going to cut out the center to match the newer 2003 gauges. I'll post that pic tomorrow.

looking good!

Looks good.

There is a local '71 truck with the Duamax long frame conversion also. He took two cabs and made a '71 extended cab

**Dieselwrencher** · 10-12-2012, 02:36 PM

Nice work on your support, and that is one awesome 69 Chevelle Dude! Congrats!

1tonwannabe · 10-13-2012, 03:28 AM

GSP7 is the 71 truck on this site? I would like to see a pic of it. I thought about doing an extended cab, but decided against it.

Okay here is what I'm doing with the dash. I want to use the 2003 gauge cluster. I had to add 2 inches to the top of the dash opening to fit the cluster.

1tonwannabe · 10-16-2012, 06:20 PM

Once again sorry for the blurry pics. Here is a pic of the other side of the dash.

1tonwannabe · 10-16-2012, 06:27 PM

I still need to do some finish work on the metal.
My Uncle is a machinist so he made me a dash panel that resembles the 1972 panel, but it's 2 inches taller to fit the 2003 gauge cluster. Our plan is to remove the inner part of his panel, and make a plate that will bolt to his panel. We have not done that yet. I plan on finding some wood grain decals to put on it so it matches the glove box door. The truck will get all the Sierra Grande trim on it.
Here is the panel.

1tonwannabe · 10-16-2012, 06:29 PM

The steering column is in about the same location as the original column. I will need to change the Chevy horn button to a GMC one.

1tonwannabe · 10-16-2012, 06:32 PM

I'm going to have to take a break from working on the truck for a week or two so I can get my CJ5 ready to plow for the winter.

1tonwannabe · 10-16-2012, 06:35 PM

The 68 shortbed Chevy is my brothers. It's got one of the nicest cabs on it that I have ever seen. The doors aren't that great but the side glass has a nude chick engraved on it with a playboy bunny logo on it.

I doubt it.

I think its Fat Jacks truck, but Im not sure. I havent seen it lately. I checked it out in the grocery store parking lot

RatRod68 · 10-17-2012, 07:00 AM

the custom panel looks great, and will look even better with the Sierra Grande package. What are you going to do about the dash pad?

**hilljob26** · 10-17-2012, 02:01 PM

lookin good,,,i have a feeling this is what i will be doing when i build my shortbed next

1tonwannabe · 10-17-2012, 06:38 PM

I might round off the right side of the dash so it blends in with the passenger side. I am going to make a piece of 16 ga. that will go over the dash and follow the contours of it. I will weld on studs to it so I can bolt it to the dash. Once I make that, I'll either use carpet padding for my pad and wrap it in leather, or I will let a pro do it.
I might come up with something else later, we will see. That part is a ways away.

RatRod68 · 10-18-2012, 06:49 AM

yea, i know. I was just curious

**Dieselwrencher** · 10-18-2012, 07:52 PM

Nice work. Your brother's window sounds interesting.

1tonwannabe · 11-13-2012, 07:30 PM

I put the Chevelle in storage. Now I have a lot more room to work. Here is a side view of the truck. I plan on putting a step bar on the truck to cover up the frame a little.

1tonwannabe · 11-13-2012, 07:32 PM

I got my core support mounted. I made some brackets and I used the original 1972 core support mounts and polyurethane bushings.

stanton77 · 11-14-2012, 08:20 AM

Looking sweet.
I was wondering if you're planing on running the IFS up front or swapping it out for a solid axle.
I'm doing a similar swap but in the burb flavor. 72' on a 2000 chassis. I'm debating whether to keep the IFS or swap in a 79' Ford HP60 that I already have sitting around.

1tonwannabe · 11-14-2012, 04:40 PM

Thanks. I think if I lifted my truck, I would swap in a solid axle. Not sure yet. Those wheels on the Burb are awesome.

1tonwannabe · 12-05-2012, 07:42 PM

I'm back to work on the 72. I put in new lights in the garage, since it gets dark so early.
I started mounting the bed. I removed the cross members from the bottom of the bed floor. Since I was going to have to notch the cross members I wanted to use a thicker beam. I used 2"X2" 1/4" square tube. Probably a little overkill. I had to figure out if I wanted to weld the beams to the frame and bolt the bed floor to the beams, or weld the beams to the floor and bolt it to the frame. I decided that since I was notching the beams, they would be stronger if I welded the beams to the frame. I was worried about the frame being too rigid if I did this. When I laid out the beams on the frame, there was a frame cross member there anyway, so I figured it was okay. I still have one more beam to make but I had to put the bed on to measure for it.
