What you are looking for is an Aftco UB-6 Aluminum Bent butt for the 130. That butt will cost more than you payed for the rod but its what you need. For the 80's, you will need the UB-4 model.

those are the aftco aluminum butts. The silver are the cheapest and they go up from there. If the builder built the rods right, the 130 will have a UB6 size ferrule and the 80's will have a UB4 size. When you buy the butt it will come with a ferrule, so you'll have some extras, just screw it on and your ready to roll.
ps...i'll take the extra ferrules if you discard them
also, if you want to go cheaper get hte American Tackle brand, same fit and all, i dont even know if there is a difference butt i prefer Aftco.
