I installed a Rev B shaker into my Spidey a few weeks ago and it works great. I did have one small problem with the molex connector on install though... The molex on the shaker had a pin plug (knockout) in the wrong spot so it wouldn't hook up to the games existing shaker molex. Simple fix, just pop out the tiny pin plug and then they can go together. Not sure if this problem was a one-off but I thought I'd mention it if the problem is on other units.
By the way, when I first installed it and started playing I thought that maybe I hadn't done it right since there was no shaking. Nope, I just wasn't hitting enough good shots. Once I started a few ramp combos etc she kicked in and worked well. In fact I really like that it doesn't shake too much so that when it does you know your doing things right.
