help with 1987 b2000 rear end and brakes

hi first time here new b2000 owner my problem is the rear end has been swaped out and its differnt and i can't find any id # on it the brake lines go to pass side then runs out of that wheel cylinder to drivers side the pass wheel cyl is leaking any ideas thanks

See for Mazda part numbers

Most likely can order through sponsor , he'll want your VIN number.

the brake lines go to pass side
UB3943650A $16.90 list

runs out of that wheel cylinder to drivers side
This might not be available any longer. Its number "might be" UB3943660B.

That's stock that the brake line feeds into the passenger side, then feeds from the passenger to the driver. All three of my trucks were like that, and the rear end I recently got is like that as well. That's normal...

ok thanks alot love the truck and wanting to get it on the road thanks again
