I am trying to find the size of the outside frame C channel beam on a mid 90's dual axle trailer for a Panterra II. I need to buy some U Bolts to attach a bracket, but my boat is in storage 2 hours away. I am thinking either 3 1/2" or 4", but 4" U bolts seem very hard to find around here.
I have an 02 PIII with tandem trailer. I think it is 3" channel.
I went to a boat dealer yesterday and measured a trailer of a random brand and it was 4” so I’ll bring a pair of 3&4”. Thanks
Just in case anyone does a search in the future, my 1992 is 4”
most spring shops can make u bolts also
