ANY Monza/Astre Wagon is a rebadged VEGA body---GM never made a stand alone body for the wagons---the Monza notchback and hatchback are not the same body as a Vega--- they use/shared many of the same components and had many similarities but they are not the same cars---Also the Vega 4 cylinder engines were horrible to try to start in extremely cold weather. Because of the iron head alum block set up the spark plugs would actually cool down at a different rate and you would get ice particles on the spark plug electrodes thus preventing the engine from firing on that cylinder... The number 5/7 plugs on V8 Monza's were not that difficult to change even tho the steering shaft/ power brake booster was in the way--- you just needed to cut a plug socket down to about 1/3-1/2 the normal length and then use a box end wrench on the socket and it came right out--worked part time at the local Chevy dlr and zone rep lost a big bet with me that I couldn't replace R&R a set of plugs in under 7 minutes--- You are right they were flexi flyers I had a Vega hatch put in a a used 406 CI sprint car engine mated to a Turbo 350 and had a Mopar 8 1/4 rear with 4:10 gears 1-2 shift it would pop the hatch loose--- drive it normal and no problems get on it and it would pop every time--that Vega even had Factory AC which we hooked up after we got the correct engine compressor brackets from the Monza--FED 387
