Before I spend money....
Has anyone driven on these?
Are they any good?

The first question you'll want to ask yourself is, what do you expect them to do? What unmet need do you believe they will meet?

Replace my wornout end-links. I'm curious to see how long people have been riding on them and if they last...

My 1990 240SX is still riding on all the original front end [and all other chassis] bushings, but I have only 104,000 miles on the car. I guess the question is "Is age or mileage the governing factor?"

I'd just go with standard replacements from any auto parts store. No need to re-invent the wheel if your factory style is working fine.
