Hi all, i'm replacing the stock parking brake drum on my FJ55 with a disc conversion i got from man a fre (http://www.man-a-fre.com/parts_acces...akeconvkit.htm). i got my drive shaft off, but there's a bolt in the center of the parking brake drum that is stuck pretty tight (see attached photo). Is there a trick to getting it off? i've tried an impact wrench, wacking a really long wrench with a rubber mallet, and even torching it to no avail. any suggestions?
