Thanks- looked it up and also found a bunch more! Apparently the parts we need are readily available and quite cheap (suspension shackles). The trailer has been well used, and the suspension system looks quite worn. Hubby was hesitant until I could find out the parts were available but now it looks like we've got ourselves a trailer. It's going to be a project, but I got it for $500.00! It's not really pretty but it's solid and everything works- it is insured and she still uses it, so there's not that much wrong with it.
