I bought all new window and door rubber back when I lived in Germany. If I'm not mistaken, I bought it at
www.opel-classic-parts.com out of the Netherlands.
I did all body mods also back in Germany, at a time when I couldn't even spell "OGTS"

. The rear part of the wheel "flares" were part of the Ascona A rear spoiler (from Lenk) that I completely cut apart and put together different, and the front parts are my own creation - in sheet metal! The top of the rear wheel housings are original, and large enough to have the 205/50 on 15x7 BBS Junior wheels underneath it.
Motor is a 2.0-16V out of a Calibra, with less than 10 kmls on it. With a few mods (hot but not too hot cams, the Lexmaul RAM Induction, big 4-2-1 headers) I expect around 170 hp. Gear box is a Getrag 240 out of Manta B OHC or Rekord E OHC.
I moved to the States in 1998 and brought all parts with me.
I planned on uploading pictures for quite a while but never feeled (felt) the need to do it NOW...
