Re: 1964 GMC "crustine" semi-build.

I'm using Rotella 15W-40 in my 478 as break in oil because it contains zinc, so why would you need to add additional zinc to it?:helpsign:

TJ,

If you think a brake line hose is going bad, change it as soon as you can. I had one go out on a 64 GMC pickup with a single pot master cylinder while coming back from a trip to the mountains with a load of trash and lost all hydraulic brakes. I was saved by the emergency brake that operates the rear wheel brakes manually. A few weeks later, the emergency brake cable broke, so I was very lucky. This was a wake-up call about how important being able to stop is. I have since replaced all brake line hoses, put in a new emergency brake cable (made locally and works great), and installed a dual pot master cylinder (where the hardest part was bending a new line to fit under the motor).

Re: 1964 GMC "crustine" semi-build.

New tires came in today! And here's a picture of the new rims!

Re: 1964 GMC "crustine" semi-build.

Thanks man! Unfortunately the rims are off a ford, but I will grind the blue oval stamp off and the curse will be lifted. :thumbsup:

Re: 1964 GMC "crustine" semi-build.

Well I got Crustine's new tires mounted this morning !:thumbsup:

Re: 1964 GMC "crustine" semi-build.

Hey TJ! Those ford wheels bolted up right? I might have to do that. I'm hating life with these 15s and GMC rims are tough to come by. What were they to originally?

Your new tires look SLICK! :thumbsup:

Have you considered just going with a taller tire for the 15's? These are almost 32 inches tall and you can get that size with a 15 inch rim. Thanks man!

Re: 1964 GMC "crustine" semi-build.

Pep. You have 6 lug wheels. TJ has 8 lug. Put some 31-10.50 -15tires on yours Pep. Easy peasy. I just put some goodyears in that size on my 82 f150
