I have had aftermarket shifters before where the shifter comes lose and falls off because of the Allen head not holding it good enough. Does the MGW shifter hold? I notice the Allen holds the shifter
use a small dap of blue loctite dude.
the pro 5.0 does use two allen head bolts to hold the upper portion to the lower portion of the shifter mechanism. i just had to fix mine about a week ago, because one of those bolts snapped right in half when i went to shift into reverse. it turned into a limp noodle with only one of the bolts in there. I'm just lucky it broke when i was stopped, and not hammering through the gears. easy fix though, even got the new bolt for free from the local parts store...
reading over again.... are you talking about the actual shifter mechanism, or just the shifter to handle part?
i couldnt find their website, but are you talking about the 2 allen bolts shown here, on the upright portion of the shifter?
if that's what you're refering to, mine never came loose in over 2 years. but the upper bolt just broke on me.
