Vacuum advance

I don't get too impressed by the BYB info. They don't give steel gage IIRC, just makes claims of the box shape being superior.... which is nonsense. It all depends on the gage and steel grade, how the slide attach to the platform, how the load gets placed on the column, etc. If you think BYB is expensive, then look at a commerical grade lift....I have just about decided to go for that versus the cheap BYB and other similar types. (But I have some heavier vehicles to service too....)

So much for vacuum advance, eh? LOL
