Help on a jon boat

[lucky13]

I need some help, 2 months ago I purchased a trailer for my 12' jon boat. The thing is, is was built for a gheenoe, so i took the back 2 small bunks off and left the front horizontal bunks and just straightened them out, it has 2 rollers running the middle that i left but i need bunks running the bottom of the jon boat, can yall help?

I had to convert a jet ski trailer into a jon boat trailer and all it took was a couple of pressure treated 2x4's and some bunk carpet (bass pro, relatively cheap) and it looks great and has held up fine for 9 years now. Brackets can be bought at West Marine or Boater's World.
