Old main sheet blocks...slightly off topic...

Any ideas on where I can source an old main sheet block setup? Doesn't matter what boat its from...I want to use it to raise and lower my Heavy Bag (105 lb martial arts training bag).

Any sources would be greatly appreciated...my back would also greatly appreciate it. Couldn't think of a better system...pull it up, cleat it and your done. Wife frowns upon leaving it hanging in the middle of the living room. It doesn't go with her "decor" nor her color pallet (it's black and bright red)...LOL...help save a marriage...LOL

I think I've seen a set of H16 blks for $75 on beachcats parts classifieds.

Wow Dave that was fast response! I'll check it out, main sheet system off of a H16 would work great...but I was hoping maybe someone had one laying in the garage that they would like to "give" to a new home LOL...I have been known to give good stuff away when it becomes obvious that I will never use it and it is just taking up space, hoping maybe there is a like minded spirit out there with an old block set up they are tired of moving around.
