Today me and pops headed up to the swap trying to unload some unneeded junk. We didn't sell much but pops found some treasure a nice springer with a weird extensionon On the bottom of the legs whoever extended it didn't ruin it under the tube layed the original legs. A little cutting and grinding and she is almost back to stock...I was stoked no super chop job just good forks hidden swapmeet treasures thanks dad
