Looking to see if anyone can measure the hardtop bolt pattern for me. Mainly looking for the width between the two bedsides and the location of the first hole on each side. Width is the biggest one though.

My new bedsides aren't drilled and I'm getting ready to mount the softtop rails. My hardtop is hanging 14' in the air and can't get an accurate number off of it.

I’ll be outside in a little bit. Is this for a 76-87? Sorry, I just realized it is first gen thread

Yeah it's for a 1st Gen.

Single or double wall doesn't matter. Just need some dimensions to go off of.
 
My Blazer has a double wall top for reference. The first hole is 4 1/2 inches from the front edge of the bed side @ 5/16 diameter.

The remaining 5 holes are 12 7/8" center to center @ 7/16 in diameter. Not sure why the first holes are smaller.

All holes are 11/16" from inside the bed.

Let me know if you need more info?
 
Thanks!

Can you get a measurement between the bedsides? From one hole on the driver's to the corresponding hole on the passenger side. If you can't, it's not a big deal...the 11/16 from the edge is what I needed to get a baseline.

I borrower the alignment stick from work the other day and best I could come up with was 68 1/4.

I have a few of those same squares too.
 
The hole pattern is different for single wall or double wall. Just beware. Mine is drilled for double wall.
 
I measured 67 1/4 center to center.

Thanks again! I should be able to work with the dimensions you gave me.

I'm aware of that. My new bedsides aren't drilled currently. The soft top rails will work with either pattern. I just needed a baseline to start with.

My hardtop bolts come in from the bottom...and it's hanging in the air over the door. I wasn't sure if it had sagged any either. Rather than drill to fit my top and find out it isn't the shape it was supposed be, I figured it a good idea to get some factory measurements.
