Questions

[Duncan and son]

We do most of our stuff on the 67-72 trucks but have a couple of questions for you guys. What was the first year for (1) crew cabs (2) c20 & c30 with 4x4 with 454 (3) single rear wheel on c30
Thanks much Paul

1) i think 73

2)i think 78, but should verify. BTW it would K-20, K-30, not c-20, c-30 if 4 wheel drive.

3) 73, but if you mean c-30, then if c-30 existed before 73, which i think it did, then whenever the first c-30 came out because dual wheels did not come about until 73, i'm pretty sure.

454s were not made available from the factory on the K-series until 1981.

C30s have been around since long before 73 but 73 is when they came out with the c30 equipped with an 8ft bed before then the shortest factory 1 ton was 133in wheel base the only single wheel c30 before 73 and I'm not 100% sure on this I think they made a 1 ton long horn model 78 was the first year 4x4 was available on 1tons from the factory period and I don't think it was available on models with dual rear wheels
