What should be installed first Dashboard or windscreen

#1 Post by Vincent Gillespie » Mon Oct 01, 2018 10:55 am

Hello, I should be coming up to this reasonably soon and was wondering from the experience of others which is the best installation sequence?

I have always installed the windshield glass last.
Also, if you haven't already, paint the small area between the dash pad and windshield the color of the upholstery since it can be seen from the outside once the windshield is installed and, if body color, doesn't look quite right ….

is there such an area on a pre A Greg? I was not aware. since the dash comes out in one piece, i'd install that last.

Ah, yes - Pre-A Corner forum. Please disregard my post as my experience is limited to later cars ...

Thought it might be easier with the dash out, thanks.

My experience installing the windshield with the dash in was that it was difficult pulling the cord to seat the seal in the limited space at the front of the dash. The limited space resulted in me having to pull the cord more upward and parallel to the windshield than inward toward the passenger compartment at something close to a 90 degree angle. This caused a small tear in the seal lip and ended up with me getting under the dash to try to get the seal to seat properly. Good luck! I only did it once but that’s how it went with the dash in.

Hi,

I did it without dash installed, works more easy, just like they did it way back in time by Porsche, check video and go to time frame 15:50

That is a Bt5, it's quite a bit different on a pre A since the complete dash comes out on a pre A, not just the pad. I do believe it is a lot easier to install the windshield first for reasons mentioned above.

If you are installing a radio. Put it in before installing the dash. Heavier, but a lot less hassle. The same for the glove box. …………...Jim.

Thanks for everyone's great advice, my glove box is part of the dash so that bit is sorted.

I purchased the full set of all the rubber seals from International Mercantile maybe 4 years ago and was wondering with all the new remanufacturing and tweeking of the mouldings is there any consensus as to which is the best screen rubbers to use. I have to say that so far all the IM stuff has been great and I might be setting it all up to do but I have a contact for someone to do this for me. Yep don't want the 'CRACK' 'OH DAMMM' moment so chickening out!

Thanks, also the Made by Hand was useful in as much that it reminded me the trim has to go in before the whole thing is installed, and it's been ages since I looked at & I had forgotten how interesting it is.

I used windshield and rear window rubber from Cicognani in Italy that were previously distributed by Veloce Space here in the US. They have moulded corners and fit flat.

That rubber might be worth a look because the corners are the toughest part.

Thanks for the tip, I have just ordered them & I'll let the person actually doing the installation to decide between the 2 types.
