im too lazy to read, so ill just tell you what i did...
1. cut the rivits
2. cut the welds on the back of the pin (tortch is easy)
3. take off the plate on the back side, it might be kind of difficult.
4. now you can take out the rest of the hanger...
when the whole assembaly is off the frame, theirs going to be two holes that are under the plate, one is where the pin origanaly went through, so your going to need drill out the bottom hole bigger so the pin will fit...
now once the pin will fit, the original bolt hole will lign up, bolt it in with the other plate on the back side of the frame.
now if you can, weld the pin to the back plate.
when i had done mine, i couldnt get the pin through the frame because when i went to cut the back plate from the pin, it was too big for the hole, so the only way to get it out was to cut the pin a inch shorter, so i cut the pin...
then when i put it all back together i slid some tubing over the pin, which was good because it alowed me to put a good weld on the backplate and pin.
my signature is sweet huh?
