Short wheelbase FF14 bolt info
 

I have a 91 c30 cab and chassis. It has a standard cab squarebody front with a 8 x10 bed out back. Tbi5.7,sm465, ff14 bolt. Thing is going to be my light duty tow pig for pulling a 1500lb tilt trailer with a 4000lb or less car/small truck.

This was used as a landscapingtruck loading sod and such on the flatbed. It should be ok pulling a light car around a few times a year. Eventually having a lm7 under the hood.

This is my 4th c30. But its my first one with the narrow 14 bolt. I have a 11 leaf pack and the wheel cylinder is about an inch away from the leaf springs. Which will make running monte calipers impossible(the slide pins will hit the leafs) and will make bleeding the rear brakes a fun exersize involving long wrenches with pipe extentions.

I imagine there is a diffrent then normal length axleshaft to make this narrow. Any other diffrences like diffrences in the pads etc.

The drums are actually a better choice for stopping and a parking brake. Axle housing is the same as the shafts are too, compared to a single wheel. Difference in width comes from the hub itself. Going to a disc set-up will be brought out with a spacer for clearance

wished i had kept my drum brakes on the plow truck over the disk swap . i have the parts just need to swap them back on .

but if you swap to the newer rear axles with twin piston brake calipers work better but the parking brake sucks a lot of the time .

After looking at the cost of the "standard" drw FF hubs I am on the lookout for a diffrent 14 bolt around $500. Slide out the narrow and slide in the standard.

Maybe I will get some newer brakes and good drums at $500 just needing to hook up new lines and run new u bolts.
