what trans?

in my 85 stepside I have a 93 D350 NV4500 5.9 magnum gas engine bell/use a 19 spline 11" clutch disc /the bell is nv4500 specific and hydro clutch.

IIRC the W350 nv4500 uses same bell and course 10 spline clutch disc gas or diesel? and can be 12"

my other hydro clutch bell is from a 88 v-6 d100 and had a a535 5 speed..it fits the a535/833/833OD/435 4 speeds

I also have a 12" clutch mech bell from a d/w350


if you are a 435 4 speed 4x4 the smaller hydro clutch bell works in the 91 with hydro clutch set up.

all on the shelf if you want part #s for all of them.
