964 cab roof alignment (that old chestnut!!)

[fredthechippy]

So, bear with me on this one - it's quite a complex little problem and I'd really appreciate some guidance...

I have a 964 Cab and the roof is slightly out of alignment. On the drivers side, from inside the car, there is about a 5mm gap between the seal on the roof and that on the windscreen pillar. Outside the car, the full length seal along the front of the roof is compressed more on the passenger side than on the drivers side (it makes a seal all along but just less so on the drivers side, and results in the little gap visible from the inside, which lets in water in the rain). It would seem that the roof needs to be adjusted to bring the drivers side forward more, by around 5mm.

Now, having read all the fantastic posts on this forum about aligning cab roofs, I've tried adjusting the vertical bolts behind the back-seat side panels, but this only gives a little movement. Plus, and this is the crunch, if i adjust the roof to move it too far forward, the locking motors on the roof catch on the guide plates on the windscreen and the roof will not close! So, the motors appear to be in the correct alignment, but the roof itself is a few mm too far back. The motors don't appear to be adjustable in their enclosures but I may be mistaken.

I know that the car has previously had one of the roof struts repaired (the weld is visible), but this wouldn't explain why the motors are correctly aligned (and cannot be moved further forward without catching on the guide plates) yet the roof appears to be a few mm too far back! Baffling.

Any thoughts or advice greatly appreciated.

Richard.

I can't help directly but it may be a good idea to ask at http://forums.rennlist.com/ - the 964 section may already have a thread or two on cab alignment.
