Big back window conversion? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

62lwbc10 · 10-21-2013, 09:56 PM

Hey all I recall one member taking this on but not sure what the result was. Has anyone performed this conversion? How did it come out? I imagine this would be a huge undertaking. Curious if it's really possible.

I think there is one in the projects/build threads section but may be mistaken.

Unless the rest of my cab was nearly perfect I think I would just consider getting a decent big window cab and prep it, paint the interior, put what ever coating on the bottom and swap cabs.

I think you are referring to thump16's thread.

Yes sir I was, come to think of it and I can't think of a better tutorial to send someone who is considering doing it to.

It also will very quickly let a guy or gal figure out if they are up to the task and want to undertake it.

looked thru thump's bbw conversion again.
$1200 in parts and a lot of work
but the finished product should look good, when he finishes it.
plus you get all new cab corners in and out

I think, when the time comes, I will take on this challenge.

I'm considering it too, but getting rid of the straight axle is next on my priority list.

My uncle is doing the conversion right now on a 66. The catch is that gm produced 3 cabs at the time. One was only for the small window (the truck he has). One was produce only for the big window. And a third had the small window but was designed so that you could cut the cab out for a big window. He found the third cab. It requires a lot of prep work but win carful cutting its by far the best way to go.

I had to stop work on my conversion due to my fathers brain cancer surgery. He is alive and well on the way to a healthy recovery considering his tumor was the size of three golf balls.

As far as the conversion itself, I have everything prepped and ready to weld in. Instead of using my small inner window frame I opted to use the one piece inner window and pillar.http://67-72chevytrucks.com/vboard/a...1&d=1352858580

So if anyone needs the inner window frame support Pic below, I have one in the attic.http://67-72chevytrucks.com/vboard/a...1&d=1352857140
