    Can anyone tell me what this is??

    I would suggest staying a retired Ford mechanic, or studying Pascal and researching the volume of fluid required to actuate the trailer brake controller and its effect on the system. A doctorate in Hydrology may help you. I believe PrairieDrifter called it good.

    Missing sway bar bolts. Anyone know what size they are?

    Grumba Just did some digging (see below, part no 29), all the 4WD use the same bolt. Its 3/4-10 x 3 1/4". The OEM part number is 328130. Sourcing aftermarket you should ensure the bolt is grade 8 case hardened. That length may be hard to find but a 3 1/2" could easily be shortened. Good Luck Butch

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    Virgil Wasn't baggin on the 208s. Had one in an 84 K10 and never had a lick of problem, they're a good box. Just answering the "what is a 1 ton drivetrain" question, nothing more. Butch

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    My point was that the all gear NP205s are generally considered to be stronger/better that the chain driven NP208s. Nothing more. Butch

    New to the forum, but not to Squarebodies...

    Tim Just came across this post. Attached are the diagram for your A/C system and the parts list from a 1985 parts manual. C60 is your standard A/C, C69 is overhead A/C. Sounds like you are looking for parts #8 and #9. Those tubes were not listed in the 1985 parts manual. This tells me they...

    Definitive interchangeable parts thread 73-87(91) (non-drivetrain)

    Jay Just came across this post and it appears no one gave you an answer. Generally, when the "1 ton drivetrain" is mentioned, it includes T400 (although some 1/2 and 3/4 tons also had these), NP205 transfer case (this is the gear drive case... no chain), Dana 60 front axle, Dana 70HD or 14 bolt...

    What is my new squarebody??? Need help!

    Carmen I recall, as WindJammer mentioned, that most if not all military trucks had the tan/bronze/maple interior that your 76I and 76V codes list. ZY1 shows it should be a single color, 2 tone color codes are different. Several of your RPO codes do not show up on a regular RPO list, although...

    BBC 396 wil not idle with any carb

    Adrian While trying to get this sorted out you should leave it connected to manifold vacuum for sure. By the vacuum number you mentioned (around 10") and the way described it running.... you got lotsa cam. My experience in a similar situation needed 40-42 deg advance to run good, connected to...

    Did this K20 come factory with catalytic converter?

    Jake As I recall advancing timing lowers CO, CO2 and HC. It also raises NOX but it doesn't look like they are measuring that for you. It used to be a balancing act between the four. If you are not limited by number of failures I would recommend: - New air filter, spark plugs - You can test...

    What is this 2 prong Plug above the oil filter?

    We had a new 84 K10 the Mrs drove as I was gone much of the time in the navy. One day while home, she mentioned that there a weird flashing light on the dash. After checking everything out it was 2 quarts low on oil. Truck wasn't even due for its first oil change. That how we found out it...

    Did this K20 come factory with catalytic converter?

    Post #7 is from Juke22, who I sent the parts manual pics for his 86. Post #23 from Paul @84GMCSierra is asking for charts for his 84. That's who my SPID question was directed to, just trying to help out fellow ol truck lovers. Doesn't seem right to be calling the 86 crew cab an ol truck. I...

    He said the under hood sticker was missing. I was asking about the Service Parts Identification sticker/label that should be on the inside of the glovebox door. I will list the engine code (LT9,LS9,LE8 etc).

    Did this K20 come factory with catalytic converter?

    Paul Are you wanting the exhaust system diagram from the parts manual like I sent for Juke, for your 84? If so, which engine does yours have LT9,LS9? The engine code will be on the sticker in the glove box. Butch

    Ricko is not off base with his recommendations. If you have a place that says you just need "this" (cats, or fill in the blank) to pass; you may be better off taking that route, assuming its not stupid expensive. If the guy wanted to be a butt it would all have to be near like it left the...

    Did this K20 come factory with catalytic converter?

    Juke Your truck is referred to in the GM parts manuals as an "03" body (2 door fleetside). The option label in your first photo shows it has the LT9 5.7L/350 engine and C6P heavy duty chassis. Hope these help Butch This page from a 1991 GM parts manual shows the codes "K2" and "03" for the 2...
