How much cut on bottom cup - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know on 67-72's the bottom cup can be 5/8 inches tall. What about on the 73-87's?

I have square body A arms on my blazer and I set the cup in the arm and measured how much I could cut off without rubbing.

mine are 2 inches and they're close to the one side already. that's with 2600's something smaller you might be able to cut it some.

**lolife99** · 08-13-2011, 08:48 PM

I thought it was 1-5/8" total height.

5150 · 08-14-2011, 12:50 PM

The reason I ask, and I pretty much knew I screwed up, was that my dumba$$ cut the cup to a TOTAL of 5/8 inch not a 5/8 inch off the original cup.

no problem, it's just metal. You can weld it and cut it again. That's the beauty of metal. You can cut it three times and still be too short, but then you can weld it to make it longer.

Measure once, cut a couple times, weld on some more, then measure and cut it right?

Sounds like a long process, but it would work.

So have we decided on what Keith thinks, no shorter then 1 5/8? I can buy these:

and just flip the other pieces over and weld them on. Just want to make sure the 1 5/8 is correct.

Bryan.
Make a cardboard template.
Easy to cut with scissors and correct any errors.
Then you will know for sure.

I'm confused Keith, I just need to know the minimum height on the bottom cup.

**lolife99** · 08-14-2011, 08:31 PM

Cardboard circle.
(like a halo)
1-5/8" tall.
Make sure that is tall or short enough before you cut the actual cup.

1 5/8" in my experience, too. That said, I would use a template to be 100% sure...
