brake booster help

I was wanting to put a smaller brake booster on an 83 s10 and was wondering if anyone knows of a website that sells any or is there another brake booster from another vehicle that will fit. I am having issues with the tire just barely hitting the booster and brake lines. thanks

Walter that is a known problem We sell boosters for that application. Here is a direct link for you.

The measurements that you have up is that the diameter of the brake booster.

Geo Metro booster or a 7" booster will work. You will have to modify the firewall for the Geo booster. I am not sure about the universal booster.

thanks for the info Chris. Looks like he'll probably just go with a universal one

Yes Its your od size of the booster.

sean- how much modifying would I need to do to the firewall if any to make the booster work and would the stock master cylinder bolt right up to it. If it won't then I might need to buy one from you to make it work

Basically drill the holes a bit bigger. When you order you will need to make sure you get a brake pedal eye and pedal rod extention also. Your master may work I do know that older masters have bolted up to these before, But if not then I have a few instock ones that we can send you.

yeah a geo brake booster or a cavilier brake booster will wor. they r both 7".
