Learn something new every day. I never considered that when it came to the .125 vs .136 bolts. Normally, stupid stuff like this tends to bite me in the butt but this time I inadvertently made the right choice by going with the group buy bolt. Just another example of what a great resource this forum is for neophytes like myself.
