Convert a roller trailer?

I want to restore the trailer for the 78 Ski Tique. I want to know how you would convert an I/O roller trailer to accomodate the boat while I work on the original trailer.

I'm pretty sure I can make it work, just want to know if anyone has done something along these lines. If you have, and have pics, that would be great.

Thanks,
Mike

Just did it last weekend. Our 86 was bought without a trailer. It made sense since we planned never to leave our lake and the marina provides great work. But things do change. I shopped around for trailed for inboards and if I WAS able to locate one the owner wanted to much to part with it. I know several SN onwers who complete this same trialer conversion project. I bought a conventional trailer with rollers. You can unbolt or use a cutting wheel to remove the rollers. Becareful not to cut any main cross members. We made up some basic L brackets & ran 2 2X16's up the middle of the trailer. We drilled and bolted the brackets to the frame. You will need to take some measurements a few times to ensure proper clearences. You can get a good look at similar trailer by going to the nearest marina and look and thier multipurpose work trailers. It should have a similar bunking configuration. I think we spent more on the beer than the materials needed to convert the trailer to rest the boat.
