I had a set laying around. Honestly the trailer is hard on them. I've already had to replace one, with the other cracking now. There is no direct fitment of course. I took a set originally ordered for my 80 and fabricated the mounting solution. I think I need to weld in a pad on the frame for them to contact more cleanly. The actual Timbrens are mounted inverted on top of the axle verse the standard frame mount layout. Other than converting it to 12v LED lights this is by far the best mod I've done to the trailer to date.
