Gentlemen:
When you say “half is not there anymore” – I assume you are referring to the availability of specific parts. That is not unexpected to me. GM continues to discontinue supply of older model parts. In years past the repro aftermarket fulfilled the need for their replacement.
Today the market for 53-62 parts is many decades into maturity. 63-67 parts market is also decades old. 68-82 part markets are also. In 1979 I was already making earlier C3 parts. These markets are saturated, matured & few will venture a repro that only fits a few models. Especially for the later year 68-82. The risk does not produce the reward, as the pool of sales is limited & the inherent model value does not support expensive replacements.
Many of the 1979 Engine parts are available from other GM carlines, especially V8 Chevrolet.
I dreaded the thought of returning my 1979 to US Connecticut emission standards. When in bought it in 1980 it has true dual exhaust, no smog. This 4 speed L-82 may have had some other engine enhancements. It was much quicker than the other cars. My wife sold it when it was required to pass emissions. This 1979 had a very interesting heritage.
