Spring perch width???

[MNTAIR]

Does an F350 rear axle have a narrower spring perch width than an F250 ????

Only if it's a cab and chassis model.

We found this out the hard way bought a f-350 rear end dually to put under my
sons truck did think about width until got ready to put it in,had to have welder
come to house grind off perches of f-250 and put on f-350 housing,also found out shock mounting is different,back came welder to weld shock mounts on.
not knowing these little tidbits costs us about 1/3 more money to put dually
rear end under his truck,thanks
