i got a 9" from a merc that was mid 70s with the tow package. i use to have a stock wab housing and now have the older strange 9" pro cast third member with 5/8 bolts. i have had it in since mid 90s it went rite in no modds just drill the leaf spring holes for the bigger pin. it is unbraced and doing well. it was a cheap find at easypull and save. there is still a lot of money in to it between the gears spool axils 3rd member but it is nice that i have no worries for the times i have been running.
