Body mount issue

[spearchucker]

I'm installing the body mounts for my 89 Blazer and ran into a problem that I haven't seen raised before. The body mounts I ordered from you are for an 81-91 Blazer. The problem is with the number 4 position, next to the rear wheel well. The carriage bolt I removed has the square portion of the shank that extends from the head down about 1/2 inch. The supplied 2 1/2 inch washer that goes next to the floor won't go past the square part of the bolt, and neither does the 1 5/8 inch supplied sleeve. So when I have the body mount installed and insert the bolt it sticks up from the floor by about 1/2 inch since it can't go past the washer. /forums/images/graemlins/screwy.gif
So how would you go about making this fit? I'm thinking I should enlarge the hole in the washer and then grinding down the square portion of the carriage bolt so it will fit through the sleeve.
I have never heard of any one else having this problem, but maybe that's because many people also install a 1" body lift./forums/images/graemlins/dunno.gif

You probably have this done already but your solution sounds like the way to go with this. Maybe not all the carriage bolts are the same?

Yep, I already did this. Just enlarged the hole in the washer to 11/16 and rounded the carriage bolt slightly, not as much as I originally anticipated though. /forums/images/graemlins/thumb.gif
Why don't those washers come with a larger hole in them and why haven't I heard of anyone else having to do this?
