Your '67 (just like mine) with the 1.1L motor would use the same spindles, hubs, rotors and bearings as any disc brake Kadett B from 65 or so through 71, which is all the same parts as the GT.

The calipers are different, as they have a smaller bore, but look and attach exactly the same as the ones used on the 1.9L Kadetts and the GTs. You can install a matched pair of the 1.9L calipers from any of the GTs or the 1.9 Kadetts or even the Mantas on the car, but the brake pedal will move further down before actuating them and it might do some wierd things to your front/rear brake bias.

Brake hoses are the same as any disc brake Kadett or any GT.

Opels Unlimited has front windshield seals as well, if you can get ahold of them.

Any shock that will fit a GT shoud fit your car, but with the 1.1L motor you actually have a bit softer springs than most of the GTs and other Kadetts, and your car weighs less. This might mean that a gas-charged shock will cause a noticible increase in front ride height, and will for sure cause a change in handling that will be more pronounced than on the GTs. That means if someone says "these shocks are really stiff" about a particular type of shock installed on a GT it will seem really, really stiff on the Kadett. Just something to keep in the back of your mind.

FWIW, I have a '67 Kadett 1.1L Coupe myself, along with a '69 1.1L Fastback, '70 1.1L sedan, '70 1.9L Wagon, '71 1.9L 4-door, and a gaggle of non-Kadett Opels as well. The coupe is a great body style.
