If you can find a hydraulic clutch setup that would most likely be the easiest way to go. I'm not sure if you'd have much room to mount the resiviour though. I'm saying to go w/ hydraulic because you'd have to weld in the brackets and mounting points for the old style clutch linkage. either way you go, if you decide to do it, take lots of pics, you canput them together and might be able to submit them to Roundedline to add to Tech forum. Theres probably a few of us in here that would like to see how it's done.

I am assuming your truck is an 85 from your screen name. you can swap it over. Your best bet would be a donor truck for all the parts hydraulic or manual. 85 would have hydraulic form the factory. You will need the bracket that holds the clutch and brake pedals as the automatic one is not made for a clutch pedal. This braket is held up by the two large studs that also hold the steering column up. and the other end is hel by four of the six bolts that hold the brake booster on. The older of these brakets are standard thread on the outside, and the newer ones are metric. The older linkage style you will need the clutch pedal, bracket that is rivited to the frame and you can bolt it to the frame of your truck no welding for any of this project. There is a arm that goes from this bracket to the ball that threads into the bell housing. ( Manual bell housings and hydraulic bell housings are not the same. ) There is a rod that goes from the arm to the clutch arm, there is a rod that goes from the pedal through the floor to the linkages above.
As far as th hydraulic set up you will need the bell housing salve cylinder, master cylinder, both lines, and the clutch pedal it self.
I am sure I probably forgot something but thats the basics.
What are the plans for the olds 350 and TH 350? Whats in your truck now, 305 or 350, 4.3?

You might already know this but incase you don't, the 350 Olds is not the same as a 305 or 350 / small block Chevy.

They are a big block B.O.P. Buick, Olds, Pontiac, bell housing bolt pattern. Nothing from them to a small block interchanges, totally diferent motor. They can be put in C K series trucks but you need everything from the donor car.

i think that the tranny that is coming with it bolts up to it b/c it came out of the same car.

I saw that in your earlier post. It still will not bolt in directly. motor mounts are diferent etc. The closest thing a 73 - 87 chevy truck came with to a olds motor from the factory was a 350 diesel.

It can work I have seen it done quite a few times. Just letting you know its not a pull and drop is all. I have a 403 olds thats been punched 30 over cam etc. with a TH400. I have been looking for worthy a C 10 to drop it into.
