Well, likely you do not have PB. To tell if you have PB, look for a booster diaphram behind the master cylinder in the engine compartment and it would have a vacuum line to the manifold. Also, the lid for the MC should tell you what type to use, but I think it is DOT 3.

Good luck.

Should be DOT 3...

Stock could have had power or manual brakes. Do you have a brake booster on your firewall behind the Master Cylinder?

you probably have Dot 3, however you may also have Dot 4. Dot 4 is compatible with Dot 3 it just has a higher boiling point. Do not use Dot 5 which is silicone based and not compatible with the glycol based fluids.

I have only purchased DOT 4 for that last 15 years. It has a slightly higher boiling point which is needed if you go to Altitudes and as a bonus it does not absorb water vapor as quickly as the DOT 3. There is not downside to going with the 4 and a couple of ups, so why not.

DOT 3 is will work fine. DOT 4 will do well as said above, plus it won't remove paint when it spills or leaks.

I haven't tried it myself, but have been told it more than once by good sources. Anyone on here know first hand?
