roller to bunk trailer

[rebs]

do you guys think these are strong enough to put bunks on for my 19 foot superfisherman 190 ?
has anyone ever used these bolsters on a trailer ?

I'd rather see you use something like these: http://shop.easternmarine.com/index.cfm?fuseaction=catalog.prodInfo&productID=5364&categoryID=223 if you take these, and drill holes where you need them for a U-bolt that wraps around the crossmember to attach to. I'd be leary of the slotted-style, and the possibility of them slipping out of position. This store has different lengths, too.

Go look at a Shorelander they use a bolt on style bracket, and if it similar I would suspect it would work
