My truck is a 79 c20 454/th400 3/4 ton. Its interesting because this truck has nothing you have except the canisters. The 77 I had, same engine, 3/4 ton had everything you have including the canisters. The 77 was a california truck so I assume had all of that because of emissions. I donr have emissions to pass here thankfully. I am going to go grab the 77 service manual I printed out and see if there is any info in there on it. Its sometimes hard to say whats what with the many decades of use these trucks have seen to know what came originally and what didnt.
