I don't know if I posted this in the correct forum, but where can I find a bumper jack for a '70 Chevelle without paying big bucks? I saw one OPG but it was really expensive.

You should be able to find one on Ebay for $75 to $100. That is where I got my 68 jack from for about $80.

Becareful of the jacks you buy from the resto places. They are expensive and a lot of them are for looks only.

My Chevelle is a daily driver, so I want it to be reliable.

Why not just carry a small floorjack in a case? Quite a bit safer. JMO

That's probably what I will end up doing. I still want to find a bumper jack though.

I have an original in my 66 for show, but carry a small hydraulic.

I got one from Hidden Valley Auto Parts, Maricopa, AZ. Very reasonable Original. Just do a web search for Hidden Valley Auto Parts, email them they'll give you a quote, they ship too.
Just my 2 cents Good Luck
