Trailer for 1968 19' SeaCraft

[crsavage1]

In need of a new trailer and an aluminum has come up locally which is rare for my neck of the woods. It's a LR-AB203600102TB1 single axle version with a capacity of 3600 lbs. and capable of carrying a 20'. Issue is, my 19' has a bracket which I assume will put it out of the the league of this trailer? Tried searching but most manufacturers don't mention whether a bracket makes a difference. Only reason I am even checking it out is because it is local. Ohio is not great for finding aluminum trailers...

Thanks for any insight.
