I have a set of stock 71 spindles and rotors I would part with. Where are you? Shipping may be too much. I also have a booster and master cylinder with proportioning valve.

are they 5 or 6 lug? will they bolt up to teh 69 or will i have to change anything else.

i live in alaska zip code is 99507,

how much do you want for the setup?

**1971Stepside** · 06-05-2003, 03:09 PM

They are a five lug set up. I checked and my booster is off a 3/4 ton. It will bolt to a 1/2 ton though. Let me know if you are still interested. I would say $50 for the whole deal plus shipping. I have no way of knowing what it would be, but I be a lot. Spindles, rotors, and boosters are heavy!! LOL

no calipers? can you weigh it? i normally just use a household scale. step on to see how much i weigh then holding the parts step on it again. subtract the 2 and wally. then i go to UPS.com add 5 lbs for shipping material, put in the zip codes and is usually within a couple bucks of actual cost to ship. If you dont want to do that give me your zip code and the weights and i can figure it out.

No calipers. I used the old ones for cores on new ones. I can get the weight for you, but give me a little time.

ok thanks

forgive my ignorance but im just starting into trucks ive been an avid 240z guy for 15years.

will these spindles bolt right up with no other mods or different parts? what i mean is i just remove my brakes remove my old spindle, install the new spindle, rotor and calipers and i have disc brakes up front? and as far as the booster goes that just goes between the brake cylinder i have now or will i need another master cylinder?

any suggestions for the rear?
i currently have a leaf spring rearend installed with drum brakes, the rearend itself looks like it originally came from a truck that had coil springs and whoever installed it got the pinion angle way wrong. Is there a rear end out there that will just bolt up (chevy, ford) that allready has disc brakes?

well thanks again for the info

You will need to change out your lower ball joints to 71/72 models. As for the brakes there will be some lines that will need to be changed. The front calipers will take a different line I believe than the 69 originals.

I will ship you the booster, master cylinder and proportional valve if we make and agreement.

For the rear I would begin looking for a 71/72 12 Bolt. It will be a 5 on 5 lug pattern and bolt right up. There are some Ford 9" rearends from late 70's Continentals that have 5 on 5 pattern and disc brakes. You should post a thread on the General Discussion Forum with these questions to get more info. Or use the search function.

Welcome to the board and I will try to get some weight guestimates for you. To be honest I bet you could find some closer to home cheaper. I don't want you to feel ripped off.
