Weight and the single wall has two interior lights, other than that Ive never really looked even though I have both.

The double wall top has 2 layers and bolts from the bottom up, single wall is 1 layer and bolts down into the bed rail

Also I believe you'll find most of your single wall tops were for CST's since they bolt from the top down into the bed rail like Berno mentioned, so you don't have to remove your rear interior panels to take the top on and off.

Leads me to believe the double walls were more common on your lesser optioned blazers (aka: no CST)

[JBerno]

Not sure on that, mine is a CST and it had a double wall top

If you order the weatherstrip around the door windows, you'll find those are different too.

I believe the double wall came first and the single wall was a later option. It may only have been 72, but I'm not sure on that.

[old man jimmy]

they changed from double wall to single wall in 72. But most of the early 72's still had double walls. They used up what they had on hand before the change over.

thanks for all the help!

Has anyone tried to modify there double into a single wall? that thought crossed my mind last night and wondered if it could be done. singles are hard to come buy and almost everyone has a double.

I have read that Double wall tops do not have dome/cab lights, however, mine has two. Any thoughts?

[briank]

That would be a single wall top then if I'm correct. How are the bolts installed , up or down?

My bolts install from the bottom of the rail into the top. Bottom to Top.

My brother had a single wall and I have seen both single and double wall tops before, I`m 99.9% sure I can tell the difference......

I`m sure I have a double wall!! I`ll take some pics this weekend.

My top has two dome lights on the drivers side above the left rear window.

Maybe I have some SUPER RARE SPECIAL ONE OF A KIND TOP...but I bet not!!

[blaze92]

mine has the two lights on the driver side but also bolts down into the rails from the top.its confusing me cause i dont think my truck is a cst. i have all the original documents and booklets that came with my truck brand new and no where did i see anything about a cst

You have a single wall. And it has nothing to do with being a cst or not. It's just the change they made in 72. Like I said before, they put out a lot of 72 with double wall, till they used up their stock, then they went to single wall.

Come down to phila., they are laying in my back yard

Also, some 72 model year had both mounts for single and double wall tops

How much weight difference?
I have the chance to swap my double wall for a singe wall top. Depending on condition, I may go ahead with the swap....

[Bentblazer]

If I remember correctly bolt holes in bedsides are different for those who want to change from double to single wall. (FYI)

I think its around 100 pounds give or take.
yes the the hole locations are different but drilling holes for the single is simple and then you can just use nuts under the bed rail.
