That explains it!

I bought mine from Fly-N-Hi (the company I work for is affiliated with them = drastic discount) - but I guess the discount wasn't that great since now I get to drill out the holes to .5" and buy new bolts <img src="/forums/images/graemlins/wink.gif" alt="" />

Thanks for the info, that solves my problem
