Hey Junkman. You are really close. The chassis is a Sept 1968 Chassis which started the 69 year model. And the engine is a 1600cc engine built between Aug. to Dec. 69. My guess is the engine is probably not original to the car but that’s not uncommon. Folks swapped engines easily back then and a lot still do.
