Mounting IBIS Knock Outs on Standard Slant Back

Here is what I just completed. I wanted to mount the IBIS Tek knock out windows on a standard slant back M1026 on a budget. So what I used is a standard soft top window frame I had laying around collecting dust. I cut out the back half of this frame. This allows the mounting of both frames to be a smooth docking. I removed the hinges off the vehicle and installed weather stripping. I drilled out on the outer window frame three 1/2 bolt holes so It could mount to the inner frame with 3/8 x 3" bolt to pass through the outer frame and mount into the inner frame. I also installed extra weather stripping into the outer frame. This gave that extra seal and proper spacing so that the turn handles will lock into the inner frame.

I cut out some flat stock to cover up the spacing

You can see here the handles lock into the original frame with a tight seal and correct amount of pressure to seal

It turned out pretty good if your on a budget. Right now I awaiting the wiper extensions to mount my wipers.

Cost:
$400.00 windows
$35.00 seals
Window frame spare and on hand
This is the NSN for which window I used

Went for a test drive and had no wind leaks. I had to move the mirror brackets to the front mounting holes to allow the mirror to swing forward enough to clear the windshield. The reason is because I have my vehicle parked in the back yard drive and have a car port to drive through that allows only 1 inch on both sides so the mirrors so I need them to fully swing in. Also mounted a 5/8 bolt to tighten down the side plate on top and plug a hole. Also in the picture you can see the weather stripping between both windshield mounts on top.

Just completed road test and leak test with a water hose maxed out pumping water all over and no leaks.

That's a great piece of work, I just got a set of these windows off a super nice guy on ebay. Would you have to do similar mods to install them in a hardtop windshield frame?

They can be installed into just about any frame. Depending on what type you may have. At first I installed them into regular slant body frame. Its the spacing you have to be concerned about for the lock handles to lock. I used a spacer (3/16x3 flat bolt/level bolt at Lowes) that I drilled into the handles to lock into the frame, see below:

This would allow me to screw in the correct tension on the handles for the window to seal. I wasn't happy with the spacing for the A/C vent so this is why I used the extra frame install above. If you have no AC vent then this will work.

Nice work. Looks awesome. Most importantly no leaks.

I will be doing a similar project on a M1038, however, I will be using a M1151 windshield frame along with the ibis tek window install kit, and a M1151 alloy roof with armor plates...will post pictures when completed.

It pretty straight forward either direction you approach:

* with an extension frame like I installed
* just direct bolt on with spacer screws
* the proper way with the correct IBIS kit
