Greetings from Finland! I have "tiny" project here đ So, 1.2S is carried out of the car, and I have C20NE waiting for install with F16 gearbox.
Brakes and chassis parts are from GSi Kadett 8V, also dashboard and center console are from model E. Problem was to find rear coils for Kadett D big block model, so I installed E model upper, rear coil plates in it.
I cleaned the chassis to bare metal and weld all rust holes (not too bad for 44 year old car) . Drivers side floorpan is fitted with Kadett - E repair panel. Front shocks upper mounts are fitted from VW Passat 2007, slight oval holes, that I can adjust the camber-angle. The doors lower panel are replaced, and now they are in mint condition. I also replaced the sills too, and the whole car is nearly in bare metal.
Hope some day, it will pass inspection, but a bit of work must be done before that!
Enjoy your projects! - Markus-
