Racing spindle questions

[The Stickman]

I have a chance to get a set of Nascar-Cup spindle hub assemblies in trade for something I am trying to sell. Now I would be using these on my Oldsmobile Custom Cruiser B-Body chassis wagon. My car comes with the tall GM spindle as is. How close might this racing spindle be to what I have and what are the chances of me using it? Now I would be getting the entire spindle hub assembly including the brake rotor and caliper so I am getting alot in the deal. I would suspect the spindle would be better in everyway to what I have. I also have a chance to get a very quick ratio steering box in the deal. I will post more about that when I have the ratio. Again thanx for any and all opinions or knowledge some of you might have.

From what I've found at least looking to F and A body GM stuff is that the distance from the lower ball joint to the center pin is a lot closer on the GM spindles than what is is used on the nascar stuff, similar problems with the steering arm locations.

I have adapted the floater type hubs onto the GM spindles though, it's a lot of work but doable, they are on ProBell's 67 camaro for some track testing. -Dan

Actually if you already have tall Bcar (77-up) spindles really al you could do to "fix" things is MAYBE tall upper ball joint, get Marcus at SC&C whip up a set of adjustable upper SPC control arms and buy the Kore 3 adapter plates. Ball joint may be needed to get little more neg camber gain, the SPC upper arm gives you more adjustability and Kore 3 adapters let you use Corvette brakes then 325mm rotor uses 17" wheels and 345/355 have to use 18" wheels.
Using NASCAR stuff seems to just make you work more to get the same, B cars have tall spindle already.
At best if its good deal gettem and swap/trade them for more/better parts.
As for brakes ,what kind of brakes? If its all race spec not off the shelf parts then you will need softer pads for street, proper rotors for street driving, and how about calipers, are they right for street or will you get them and have something thats either too high price to replace/repair or possibly even obsolete for part sourcing.
gotta look at "great deal" vs headaches for service, getting $300 set up that you spend $1000 on to fix/service sure doesnt beat the $1200-$1400 new parts that will surely bolt on a lot easier.
Bcar spindle is much better than most give it. and sourcing parts is a lot easier.

before speculating about anything, first how old are these spindles? are they the old SPC (Stock Car Product)? as far as I know they used 7* tapered ball joints GM uses both 7* and 10* you need to know all the mounting point locations upper & lower ball joints, tie rod end location, both sides they may be different!, king pin inclanation, spindle pin location, alot of the stock car stuff is derived from various parts from various makes because of the rules, many of the front steering parts are close to what was used on GM b-bodies mainlly 73-76

Herb Adams used to use some of the old Stock Car Products spindles and I think you did have to switch ball joints. He used the old Hurst Airheart brakes on them.

That is exactly one of the set of brakes he has. I hope to have pictures later today.

Wow, what a blast from the past for me. My first car ever was an Olds custom cruiser wagon. 1973 year. I was 16 and didnt have any money but hated walking. So I picked her up for 300 bucks and stopped walking so much. I could pile all my friends, their friends and some strays in the thing. It was great.

455 olds, quadrajet carb, easy to work on.

Some drunk dude drove on the wrong side of the road one day while my car was parked. He managed to miss the side of the car but hooked the MASSIVE bumper. There was all types of carnage on the road, his car. My bumper was bent all the way back from the large bumper bolts. Prolly a two foot section of bumper bent back a few inches.

I drove it to work and slowly backed the car up against a large concrete lamp pillar. Eased it back to push the bumper back in place. Good as new. Didnt even crinkle the chrome. DAMM they dont make bumpers like that anymore. Tore the hit and run drunks car all up (all his plastic was on the road) and I was good to go with a lil tweaking

I love that old beast. I looped it one day. Getting on the freeway, right hand turn, roads were damp with our night time fog. On ramp was angled off to the "bad" side. Spun the entire car around, kept it within the two onramp lanes. It spun all the way around so I was facing the correct way so I just went on my merry way. 16yo kid learning how to drive...

I have some great memories living with that car........... JR

There are endless Combinations of Spindle's used in NASCAR applications....Take good pictures and I might be able to tell you what they are.... I would suggest ditching the Hurst's I think those things came over on the Mayflower....

Our 69 vintage race camaro has the Airheart brakes and SCP spindles. Several versions were made, taper size and angle used on those is usually 7 degrees but larger sizes for strength. When GM went to the cast iron spindles, the started using the 10 deg tapers. Some steering linkage was still 7 deg though. I think the top UBJ that is often used is a late 60's chevy pickup ballljoint. It looks like a camaro or mid 70's Monte Carlo ubj, but the bolt pattern is wider, so it doesn't interchange with Camaro and mid-size balljoints. It's 7 degrees.
