Hey guys i hope you can help. The lever on my top isn't strong enough to lock it. i turn it about half way then it jumps like the spindle is stripped. I checked the teeth on the lever and spindle they are still sharp. so i took the lever off, put the roof on then tried to use a pair of pliers to spin the spindle it turned about half way but wouldn't budge after that. I fondled with the top to see if maybe it wasn't lining up, that wasn't it. Then i checked to see if the studs were getting jammed in the holes, nothing. what the fawk is next. help me out please. thanx
