quick clutch cylinder question for a 63 GMC

[shok]

The seller of a 63 GMC with a 305 v6 sent me some pics, it looks to me that the brake and clutch master cylinder is combined into one casting, is this so? So far the hits I'm getting while searching aren't helping.
I'm trying to be sure and considering buying one since he says its all it needs, if I end up not buying the truck I can just return the part to AutoZone afterall.
I'm attaching the pic with the part circled that started my confusion, thanks.

That's correct SHOK; they are both combined in the same unit..

Yup, that's what mine had in it when I got it.

Thanks for the confirmation, this search for a vintage truck has been kind of frustrating so far.

If you decide to buy, just make sure all the paperwork matches up. To the best of my knowledge only the 60-62 models used the hydraulic clutch. 1963-66 should have mechanical clutch linkage.

Oh yeah I always check the numbers, this truck and two others are on the list to check out later in the week. Pickings are slim around here in my price range.
I'm pretty annoyed that the ad for this truck says its a driver but only after a coup,e of rounds of email it comes out that the piston for the clutch master is stuck, that's not a driver in my book....

Mark, The GMC's used the hydraulic clutch thru the '63 model year. I didn't know that until a couple years ago myself.

Thanks for the clarification, I wasn't aware of that.

Do you guys want to see the pics he sent me of the truck? It doesn't have much to do with the topic but if it entertains I'm willing

Sure...love entertainment

I live to entertain!

Truck looks good. Looks complete, which is a big plus. Rust looks to be in the typical places, but pretty straight. What are your plans for it?

[shok]

Well I don't even own it, ad said it runs and drives great but now we know there is a clutch issue. If I buy it I will keep it simple with a good cleaning and getting mechanics up to snuff. Past that electric cooling fan, ignition upgrade, high amp alternator, holley carb and new exhaust. Then we will see how long that 305 v6 lasts before I have to decide between staying with that motor or dropping in a v8.
Of course it will snowball beyond the plans but thats it basically, same plan if I get that or another truck.

[1963c-10]

Many of the GMC V6 engines are still running and will probably outlast the trucks. It was an engine that in my opinion was overdesigned and extremely well built. I think that short of wanting tons of horsepower or torque....that if you want a tough reliable engine...the 305 is the way to go. And lets face it...its already made it 50 years.

[shok]

Well the truck I get for the most part will have a cush life of in town driving, occasionally towing another car or the possible trip out of town where it will rack up a few hundred miles.
I just don't want it to be terrible on the freeway but I'm not asking much of it, so if that motor can hang I'll be happy. I just want a truck as a support vehicle for the next car project basically.

Thanks for the link. I think I will buy the part and that way if I decide to get the truck I'll slap it on right there. Maybe the guy will be cool and help me bleed the system.
They also have a $100 dollar version which I think I might get if its really better and if I buy that truck I think I will keep it a long time. Plus single circuit brakes scare me so I want the best. Any input on the 40 vs 100 buck part?

When it comes to brake components Im a firm believer that you pay for what you get.

Yep I agree.
If I get it unless the lines for some reason look great I'll replace them too. I had a 65 Karmann Ghia with a single circuit brake system and while stopping at a light at the end of a slight decline the pedal suddenly went to the floor, the parking brake barely stopped me in time. Turns out the line going to the rear wheels was rusty and ruptured.
