EZ loader trailer question

[kraken]

Hello everyone first post ever. I just bought an 82 Wellcraft V20 inboard outboard. The trailer, an EZ loader, needs the axles replaced before I can move it. I need to know the dimentions of the axles or a part number so I can replace them. I also was wondering why this particular boat had a NASCAR type sticker on 3 points. It said NASBOAT. It looked like a factory sticker. This boat will need and extensive cleaning and some parts replaced and if anyone has a good resource site for parts please email me. thanks.

I need the dimensions of the spring plates, hub faces, and overall tip to tip measurements.
