Thought I would pass this along in case you missed it. 914 Rubber offers kit to redo your dash for $35. Precut foam and vinyl for the dash top. Roll of material for dash front metal.

I need this...

Does it go on top of the existing dash?

Nope, you have to strip it all off.

Seems like to do it right, you need the windshield out...

I took the dashboard off, putting on new dash cap.

I do need this. I was waiting till the windshield was out.
I already have the glass, so now I better order this also.
More parts for the 914 to do bucket.
