Upper ring trouble

[SgtKish]

Can someone confirm that maybe this angle is not 84°, and maybe its really 94°? In the pictureit looks to be an acute angle, not obtuse like it is saying it is.  I just want to check before i bend this angle. Thanks

That's very helpful intel, thank you. It looked like I was going to have to bend that 1/4 " angle iron front bracket, but your drawing here is good to have. You wouldn't happen to have the hole layout/ measurements? That could line me up so much easier and may help with actual placement of the upper rail. I sold my last M3 rebuild to the Doolittle Museum in SC. So I have nothing to go off of anymore. I thought that rail was flush with the door, but I can't remember really. Obviously your pic clears that up a bit..haha, but I still don't understand why it's too far in by 2 in on each side where it meets the b pilliers.maybe it's bent and I need to cut a relief in the b piller area to bend it out. Then add the new pieces from there going down the side armor and rear. Do you think you could get me a measurement across the width of the rail on yours? 1 measurement at the first slight bent at the beginning of the Bpiller, and another after the second bend where the rails would start to be parallel to eachother? That would let me know if mine is bent, and where I need to correct these bends. If you could get me that off your track, or steer me in a direction where there is a blueprint of the upper rail, I would be very grateful sir? Thanks again for the help.

Oh OK, no problem.  I checked both sides, and they both have 2 bends on the same spot that look like clean intentional bends.

Well that's good news I guess....sorry if I spooled you up!

[SgtKish]

No worries man, I'm just taking in all the intel I can get at the moment. I think you are right about it being bent though. I think when the last farmer had it modified. They welded 2 1 inch bolts on top of the rail at the first bend corner at the very front, and one at the bend you are talking about at the front of the B piller behind the pass door. I think the heat from the weld pulled those two parts in quite a bit, and that may be what's going on here. I might just cut a relief at the front corner, and on at the b idler. Then try to bend it back once I can confirm what the actual width is of the rail where both side rails go straight and parallel.

84 degrees is an acute angle.

My original perimeter rail width behind doors 76 5/8" o.d.
Front window rail width 60 1/2" o.d

[SgtKish]

Thank you very much for that sir.

Sorry i may have said that wierd. I know 84° is an acute angle. Just the way im trying to hold up this upper rail, and judge the angle. It looks like the angle should be more obtuse just past 90° a little. I shouldn't have questioned your drawing. After taking a better look at it. I believe that is the angle i need. My mistake,
Thanks again for that drawing.  I wont question your information again ...haha. Bear with me here, things are getting frustrating in the shop with this thing. Im starting to loose my sanity a little. I think i got everything i need to make it happen. Just need to know how long the rail is from the windshield to the back.

Please - question me! I'm wrong way more often than I happen to get it right.
