So far it looks like big block trucks and suburbans were fairly well optioned. The average truck so far has about 18 options on its SPID. The vehicle that has the most options so far is a 3/4 ton Chevy longbed with 25. The vehicle with the fewest options so far is also a 3/4 ton Chevy longbed with 12 options.

So far there are some options that seem to be on most of the SPIDS given so far. There are quite a few SPIDS that have some very unique options. I will give some stats on certain options next time I update.

Also I am noticing that there are different options codes for the engines within the same year. Does anyone know why there is a difference in the codes?

1969: 4L47AA
4L47AB

1972: 1L4710
1L4720

Also does anyone know why some trucks use 3 digit codes while others use 6 digit codes?
