    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

    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

    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...

    Paul This is the body type chart for 84, yours is an 03. This is the exhaust parts illustration for the LT9 engine. These are the emissions control parts. B
