Chariot Bolt On Spring Hanger Bolts 4" COC
 

Leaf springs are all rust on my Chariot 1997 trailer for my 1997 Talari. Trailer is a single axle, 17' long and the boat weighs 2200 lbs.

Looks like 26.5" springs but the bolt holes on hanger are 4.25" center on center. The trailer is aluminum, has a 6 hole frame mount but the bolt holes are 4" center on center. There's just no room to drill out new holes on the frame to fit the 4.25" new hanger bolt holes. Anyone ever come across this and have a solution?

Thanks for any help!
