I'd buy everyone I could get for that price with that kind of frame rot !!! very easy fix . The rear ..... well it's a D-35 with 4.10's ( a dime a dozen ) . All the AX-5's shift alittle funny ( grind , hard shift when cold ..... ) .
Buy it , fix it , and wheel it or sell it and put some money in your pocket for the next one.
Just google fish plate .... I don't feel like explaining it , but it's simple.
You can sell the hard doors for half the purchase price !!
