I factored in both the increase in tire depth of the 16 but also and more importantly as it turns out, the diameter and the way it affected the clearance front to back.
I bent the outside rods to make it easier to move the tire in and out. Be caerful that you don't snap them off.
Unbolt the carrier from the trailer.
Cut the two hinge pins with a hacksaw and remove the uprights (angle iron).
Cut two pieces of 3/16 x 1 1/2 x 11 inch angle iron.
Measure the hinge pin placement on the original uprights and drill a 13/32 hole in your new pieces at the same place.
On the opposite side of the angle iron piece, measure from the center of the hinge hole up 8 3/4 inches and drill a hole large enough to accommodate the chassis bolt (1/32 larger drill bit than the bolt diameter).
Bolt each piece of angle iron to the carrier. I used two grade 8 bolts, 3/8 x 2 1/2, washers and stainless ny-lock nuts. Whatever bolt you use make sure that the non threaded shoulder is wide enough to act as a hinge pin surface.
Paint everything with black Rustoleum paint.
The 16 inch tires added 1/2 inches of ground clearance. Lowering the carrier 1 1/4 inch effectively decreased the clearance by 3/4 inch from stock.
