You say the rev counter bounced about...if the needle is dropping to zero and then springing back up when the engine is misbehaving then that points to a low-tension issue (tach is fed from low-tension side of coil)...likely culprit is condenser of you are running std ignition.

The Peugeot Kugel installation seems to avoid the need for careful mechanical synchronization of thottle butterfly and fuel lever by relying on manifold pressure (with barometric compensation). There's a few parts from our turbo cars you'll recognise. Just FYI, sorry for being off topic.

Doesn't it just mean that the custom transmission bracket isn't right? The engine/box is on a 3point mounting, the transmission mount defining the flange face angle both horizontally and vertically.

From '79 the E21 was assembled locally in Malaysia - easily imported into thailand back then...not sure about the US spec certainly seems to be a more vibrant 02 community in Thailand than there is in Malaysia...here its strong fopr e30 & later but the earlier cars are rarities...

There's no doubt that the quality and stability of plastics from the 1970s was far better than today... I posted elsewhere my cars running-in sticker still going strong despite 40 years exposure to sunlight... I dunno if all the stickers were that quality and if the adhesive stickosity remains good...but I would say it's likely it's still good.
