    What year did K5's change over to hydraulic clutches? Did they still use a cast iron bell housing (clutch housing)?

    That's how you can convert the old style bell housing to hydrolic. Internet bud did that on his SM420 equipped jeep. willwood also sell a clutch master that you can use.








    I don't need no damn shop manual, I got a pornographic memory.

    I've seen that set up. thank you. I'm trying to find the bellhousing the my cousion has (he does not know the pat number or the year). It is a cast iron bell housing (which looks to be GM) With stock provisions for the clutch slave. I would rather use this bellhousing if I can find out what it came out of (Big Truck maybe?).

    85 was the first year for GM trucks to have Hydraulic clutches.

    77Chev has all the part numbers.

    I think it was 85. My 87 used an aluminum bellhousing but I sold it and the 465 trans when I installed the AA bellhousing and NV4500.

    A good firm grip is my idea of gun control!

    a bit curious why you went with the AA bellhousing when the tranny was a stock chev offering?
    is the origonal poster actually asking when they stopped using a CAST IRON bellhousing, i dont recall seeing a k5 ever having other than cast aluminum, must be a 60s or earlier thing

    Yep, the other guys hit the nail on the head. '85 was the first year they started.

    My 69 k5 came stock with a cast iron BH, so did my friend's 1970 K20.
