[1964 GP]

my 1964 GP has the 8 lug wheels and i want to put torque thrust wheels on it. But the front wheels on a 1964 GP have the brake drum bolted onto the spindle where the hub would go. (some Grand prix's had regular 5 bolt wheels)
I am looking for 5 bolt hubs for my 1964 GP but I cant find any place that has them. some places have 5 bolt hubs for a 1964 GTO.
Does anyone know where I could get front brake hubs for my 1964 GP?

You need the whole 5 lug front hub/brake drum assembly to replace the existing 8 lug setup. They were the same from 1962 through 1964 and shouldn't be too hard to find since the vast majority of cars used them instead of 8 lugs, the main issue will be sourcing a set that still has enough meat left on the drum braking surface. They bolt right on, there's no difference to the bearings or how they fit on the spindle. Of course, you need to get 5 lug brake drums for the rear wheels too. You could put an ad in the parts wanted section here on the forums.

Ok, sounds good

[1964 GP]

Ok thanks that help's me out a lot!

Hi, I was just curious if you had a chance to mic the drums yet?

[Rachelsdad]

I should have a pair from my '63 Bonneville parts car. If you can wait until I get back to NY on the 6th, I'll have a look at their condition (should just be surface rust, and I think there is enough material for them to be turned).

[1964 GP]

Ok, that sounds good, Do you know how much life is left on the drums?

[1964 GP]

All good, i'm not in any rush. Sorry about your cold, I hope you get well soon.

[1964 GP]

Also, how much would you want for the hubs? Or hubs and drums together?

[1964 GP]

Hi, did you get a chance to do anything with the drums yet?

[Rachelsdad]

You don't need hubs, as the hubs are integral to the front drums. You will need new races, however. I can't vouch for the condition of the ones in them, but these are pretty standard parts (even now).

I'll mic these drums when I get back home (as I say, 12/6).

$25 ea plus UPS ground shipping would be more than fair, assuming there is enough material to turn them and have some life left (which I fully expect).

I got this parts car in 2005. I don't recall how many miles were on it when I got it, but it had been in an enclosed trailer/portable garage in northern California for several years (over a decade, IIRC). The drums have been loose in my garage until this fall when I had to move a bunch of stuff out of that bay to make room for my '63 Bonneville to come back from the shop. They have been outside under a tarp since then. They should not be in bad overall condition, but let's see what the mic says.

I went the opposite way with my '63 in the mid-'80's, and picked up a set of 8-lugs at Carlisle one year. This is how I know how easy they are to swap. ;-)

Edit: I should have rears, as well. Let me see.

[1964 GP]

I am planing to make an order on front drums soon, either from franks or from you. Are you still wanting to sell?

[1964 GP]

So you are saying that the drums are fixed to the 5 bolt hub? or the 5 studs are bolted right onto the drum that is attached with the same bolt and bearings as the 8 bolt drum/hub?

[1964 GP]

if you still willing to sell them that would be appreciated. I think I will order from franks on wednesday.

[1964 GP]

Sorry that was confusing. I am used used to 1964 impala stuff where the brake drum and hub are seperate. So your 5 bolt and drum are 1 piece?

For the front, yes. In the third picture, below (Front_wheel_assembly_cross_section.jpg), the shaded area in the inset is all part of the brake drum itself.

Now, if new drums are available, you might want to go that route instead. In fact, Ames has them listed in catalog P25 (current, AFAIK) as their part number PR447W (front) for $139 ea, and PR448W ('59-early '64 rear) or PR449B (late '64-'70 rear) for $139 and $125 ea, respectively. I can't tell you which rears you have (nor was I previously aware that there was a mid-year change in '64). The nice things about new drums are that you know they're straight, that they have life in them, and that they don't need to be cut.

Frankly, if you want to go the new route, I'd call Ames and discuss the situation with the rears with them. Those guys are great, and can usually (80-90% of the time? better?) direct you to the proper choice for your application.

I should mic these drums, anyway, if I want to re-home them to someone, so no issues on my end whether you go with new or something from Frank's.

[61-63]

New drums are available from various sources. I bought new front and rear drums for my '63 Catalina within the past year from NAPA.

[1964 GP]

Ok, thanks for getting back to me.
I'm glad you are feeling better!
I was actually able to find a nice new disk brake set that cost me the same as franks would have.

[Goatracer1]

Rear drums for the 5 stud application are available from Rockauto for around $70 each. I used them on my own car and they are name brand.

Thank you!
