Bumping this old thread.
Wow, ancient history coming up....mate, I bought a Prolift all those years ago. Still works great, never had an issue...and that shop use, not casual home use.
Yeah I bought one a few years back when I had the Dyna also bought the orange blocks from HD which I used to just clip onto the frame and she worked ok very stable. The softail doesn't need the blocks as mentioned 5 years ago in this thread it just fits under but is very stable once in the air.
Thanks for review and comparison of the old and the new lifts. After reading that I hope I got the old one. Father in law bought it for me but I havent seen it as away from home for a while. I'll be happy with either at the end of the day as ive never had one.
