OEM De Tomaso windshields and rubbers available via Mr. Fiat

Benchu, I'm not far from trying the same thing...Any hints wrt fitting and gluing the rubber gaskets? Lee

For gluing rubber - in aerospace, we used instant-bond Superglue to build big o-rings - use a fresh cut on both surfaces to be stuck together, as a cut rubber surface seems to build an oxide layer after a short time. This degrades bond strength. Other glues will require some sort of clamp or fixture.

Superglue doesn't seem to spread well after putting the parts together, so coat 100% of the contact area with a thin layer of adhesive before bonding. Not only will the glued jint be stronger, there will be no little openings to leak rainwater.

Wow, thanks, I had resigned to using 3M "Black..." I'll try this. Any special recommendations on a knife?  I'm wondering how to avoid 'sawing' with a razor...

This "windshield event" is in my near future... I am a bit nervous about it also.  I would love to see how others have approached this.   We need a windshield sticky...

In building 10-ft OD rocket booster o-rings, we used a brand new x-acto blade each time. Rubber is abrasive... If you google 'McMaster-Carr', they have several actual kits for building o-rings this way, including a square-cutting fixture, single-edge razor blades, superglue and a few feet of o-ring stock. Making the ends absolutely square is important to avoid a twist in the glued part. Practice a few times before gluing an expensive part. You can often cut the thing apart ONCE and redo things.

Fabricated rubber pieces that are used as stationary seals work well. For o-rings that have to move and seal, it's trickier because the glued point is less flexible than the rest. I once modified a Camaro clutch master cylinder with a glued-together secondary o-ring in a piston slot I machined myself, because the piston was an odd size and the OEM seal was an inadequate cup type- just like the Pantera. Worked fine at a clutch's low operating pressure.

Mr Fiat is pretty proud of their windshields, are these really the only oem quality on the market?

I purchased Pantera windshield rubbers from Roland before he closed shop, they do away wit the trim and look more modern without going to a full glue in windshield.

...Oh, anymore I think that anybody providing any parts for the Goose is a saint...The market for Goose parts is probably one desperate person per year. 

Roger that, Lee! Larry Stock has had a few brand new Mangusta windshields and rubber gaskets for at least 10 years without a sale. I once mentioned that ALL Pantera parts vendors are a labor of love, not a profit making venture.  They could easily make more money pumping gas at Shell or Arco.
