What is the size and length of the bolt that secures the mount to the stand.Mine had washers and they were too long. I would like to replace it with the correct ones.

I believe they are 1 in. They have a thick flat washer & lock washer. I always cut the hole on the stand larger. It can save a lot of hastle getting the bolts started.

I think the mount to tower bolt is 7/16 N.C. I have heard of some of the aftermarket ones from overseas have metric threads, so check what you buy.
