Project 47 GMC

[Fat Mike]

Has anyone done a gmc to chevy conversion? I was told that you just have to change the grille and hood. I already have a grille but wonder if I could just weld up the front of the hood to make it look like a chevy hood? What are the differences in the hoods. Both 1/2 tons.

[Chevy51]

Mike, just looking in,and there is a difference in the hoods. The Chevy hood has a different angle right on the front where the hood latches. If you notice right on the front of the GMC hood there is a longer edge,than on the Chevy hood. If you are a good fab guy,which from what I see you are, you might make it work. Also I think the radiator cover where your hood latches, may be different also. Good Luck.

Hey Mike, Heres a few picts of my truck that some friends and I put on an s-10 frame in record time. I used as much of the s-10 as I could. the wiring, steering column, brake pedel assembly ect. I ended up using the rear end out of a 75 chevy pick up, only because I already had the wheels to fit.check it out. I drove this truck to calgary, alberta, then to vancouver b.c and ferried over to victoria island, a 7000 km round trip, where I met my beautiful woman standing outside her work having a smoke when she flagged me over to check out my truck. brought the woman home with me too!! lol

heres some picts for you mike, if you look, you can see I cut out the back window like you were talking about and moved it as one piece . I lowered the back window to make the bottom of the glass flush with the bottom of the door glass.

I'd suggest finding Chevy parts to swap rather than modifying the GMC pieces. Chevy's seem to be much more common, and readily available. In fact, I'd be very interested in working a trade with you, but I don't know whether the shipping costs would be worth it.

[Fat Mike]

Yukon that looks very nice! Love the frame on that truck also. Thanks for the info and I will post pictures of progress very soon.

[Fat Mike]

Today I got the frontend taken apart and it seams like there might be a few pieces missing. I just put the fenders on the ground with hood just in the mock up position. This will not be the hood I use because I am converting to the chevy grille. I was going to try to fix the grille cover but wasn't sure the best way of doing it. There are 2 tears about 3" long, so should I just put it back together as best as it can and just tack weld it up. Need some imput.

[Fat Mike]

This was a brace that was on the passenger fender. Need to know if there is suppose to be another one on the driver side?

[nebdrummer]

yup... one just like it. just mirrored.

[Fat Mike]

Thank you! Guess I am going to have to find one ASAP!

[ratty 46]

FM ... Nice start. Count me as scribed.

As for you yukon ratrod - what a love story that was (LOL).

Nice truck.

Hey Mike. nice to see the progress. how is the rear frame work coming? i posted the pictures for you. Troy..

[Fat Mike]

Troy I am doing that c-notch on my 59. Thanxs for the info thou! I did cut everything today.

[troy54gmc]

dude u are doin 2 different projects? how do u have time and money for that?

[Fat Mike]

Well, got a really nice hood of craigslist for $40. Starting talking with the guy and he has several trucks that are really nice. Told him he should look at this website and now he is a new member. His name is averagejimmie. Thanks for such a good deal!!

[ratty 46]

Nice score ....

[Fat Mike]

Starting assembling the frontend today and had a few questions. I am doing the gmc to chevy conversion and wonder if the bolts are the same. I tried to thread the grille to the side fender and they did not thread real easy. Also are these threaded nuts suppose to be removable or not.

[Fat Mike]

What is the difference between the gmc and chevy radiator shround and hood latch assembly?

[troy54gmc]

hey Mike. i dont have the hood latch assembly but i can take a picture of my gmc radiator shroud if you want. let me know buddy.

[Fat Mike]

Troy this is the one from the gmc. I need a picture of the one from a chevy.

Chevy hood latch panel

[Thadious]

GMC to Chev converstion...

Not sure if the grills bolt up... might want to make sure you retap all bolt holes first (5/16"). The grill (of course), the hood, the upper shroud and latch assembly, the latch assembly on the hood (if it didn't come with it), there are 2 panels on the underside of the grill as well to be swapped (the one from the bumper to the grill an and the one behind that) and the rad support. (The frame is slightly different under the rad support as well).

The GMC's also have the marker lights under the headlights, whereas the Chev's are in the grill itself.

Just from memory... may have missed something...

Cheers,
Ted.

[Fat Mike]

Ted I did retap everything today and everything bolted together very well. I got the grill attached to the fenders. I am still missing a few parts thou. I still need a splash apron but will probably make my own because of the old school bumper I got with bezels. Missing turn signal lights but plan on using 57 chevy turn signals. Inner fender bracket but have one located. So I think the only thing left is the chevy hood latch and shroud cover.
