Hi everyone! Has anyone got any experience with removing the windscreen frame from the body of a 3000S? I am assuming that the bolts pictured below are connected to the windscreen frame and secure it to the body.



However, having removed the rusted up wing nuts (15 below) and given the end of the bolts a hefty tap with a lump hammer nothing is moving.
The tube holding the bolt is bonded into the tub so I'm assuming that the bolt should simply slide out of the tube - but it doesn't. Am I missing something? Is anything else fixing the window frame to the body? I've already undone the 2 nuts towards the middle holding it to the dash cover (item 12 below) and can't see anything else likely to be holding it down.



Any suggestions gratefully received!

I'd guess you're fighting rust.

Judging by the state of the rest of the frame I can believe that.
On first thought with a 3/8 UNF bolt in a 7/8 tube I thought there was plenty of clearance. However, looking from the "head in the footwell" perspective, there appears to be either a washer or spacer further up the tube in which the bolt is a tight fit - so rust here could be what's holding it. Anybody shed any light on what's inside the tube? I'm reluctant to give it some welly without knowing what I'm up against.

Very often, the tubes need to be cut out and new ones re-glassed. Its a horrible job and very difficult to get right I believe.

Good luck with the job - did you get a frame ok??

I was hoping I wouldn't have to replace the tubes - I can see that would be "tricky".
I haven't sourced any replacement bits yet since I'm not sure what I'll need. The outside chrome bits are OK (will need re-plating) but some inner bit are rusted and until I get it all disassembled I won't be sure what will be recoverable or not.

It is far to long winded to post everything involved here, BUT what are you doing? and why?....several notes of warning is that NEW screens are NOT the same as OE and the whole frame will need to be re-profiled to fit, OE fitting was by hot wire melt adhesion (not something that you will want to use) and IF you are thinking of using powder coat on a completed job note that current day screen adhesives do not stick to it...Adrian@

Hi Adrian, I am trying to dismantle the screen to see what needs repairing/replacing. The glass is intact and the chrome metal bits are sound but need re-plating. The lower neoprene seal looks in bad shape and the other sealing material was brittle and coming away. Removing the front chrome strip showed a lot of rust on the non-chromed parts of the frame. I had assumed that undoing the 2 wing nuts and the other 2 central bolts that the frame would come off the body and could then be assessed to see what needed replacing.
It looks like that is going to be difficult but probably no alternative?

It is most likely best that you call me tomorrow and talk through a way forward (and I can then organise a good time to call in an evening)...I have all the parts to do the job, but even releasing the front minor bolts will allow the side uprights to fall (I measure those points before removing anything) and close the rake/angle to the side screens (this is so flexible that movement of the shell on a uneven surface causes issues). It is standard practice to mask the paintwork and saw through the uprights under the intermediate plate and remove the internal tubes from the shell and throw them away, replacing them with new.

Quick update after my chat with Adrian - seems best to try to replace any rusted parts of the frame with it in situ since removing the tubes will be "difficult" to say the least.
I'll post progress in due course.

PS - thanks for the advice Adrian.
