[only 31s]

87 410s to replace my 90 342s will these just swap in or do i need to change alot of things--such as leaf springs,steering arm,u joints-Thanks for any info----+ will this new ratio w/33s help my highway power?

700r4? youll like the 4.10s+33s. Everything should swap in, although the 89-91s typically had a 31 spline axleshaft, while the 88 and older had 28, but if you are swapping whole assembles you wont even notice it and everything should bolt up fine.

Are you swapping the entire axle assembly or just the R&P gears?

whole axle assemblies

whole assemblies-but now that ive recieved them -they need some serious love- drums ,discs you name it-i may have got a package deal on the running gear but i need to sink a GOOD chunk of money into all brakes-tires are fair + they hold air
