Hey group, I have a '70, c-10. PO said he replaced front drum brakes with discs from a '71. Original drum brakes are still on the rear wheels. I want to replace the brake fluid since its been in the system for past 9 years. which brake fluid do I use? It seems DOT3 might be the way to go, but.....I just want to get the "experts" and your opinions.

Thanks.
