I have been looking for a booster for my 70 Javelin for a while now. NAPA says they can't get one anymore. I'm not too excited about shipping the only one I have to a rebuilder. I fear I may never see it again. What do you guys think? Do you know of any sources for boosters? How about a booster that could be fitted in place of the original. Any one tried this on a 70 Javelin. Thanks Armand
