i found it when i bought it about 9 years ago........same as my 87 4x4 sub.Anything i've ordered or done was based on my 87.Now i need to read the frame numbers but i don't know where to look,can't find that info yet.And if this engine can't be in an 85 then i should be able to remove the rest of the smog stuff ........explains why i was told the etest was based on an 87.......now exempt after 20 years

I was under my 86 the other day and saw some numbers stamped in the frame on the passengers side, rear, up near where the upper shock mount is. I was putting shocks on it when I noticed it. I did not compare them.....
Im sure a square body expert will chime in here soon and tell us where the frame VIN numbers are located |

Re: HELP...1986 C20 5.7....smog removed,,,Check engine light???
Ihave been haveing exactly the same problem,
I have an 86 c20 dually converstion. Check enginelight would come on on when I went over 55 then off every time i turned ignition off. Now it stays on. I have no plug for code reading under dash. No obvious smog equipment under the hood. Trucks runs fine other than needing a break seal replacement on the dually rear end. All I want to know is that im not killingthe truck and that the check engine light is not coming on for a good reason like trans temp or oil pump failure etc. |
