88 Dually old body and 88 dually new body spindles? same? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Are the 1988 Dually (old body) and 1988 Dually (new body) spindles the same same? I guess the question is, they are the same year but different bodies, are suspensions the same? I have 88-98 dually drop spindles wondering if theyd work on my 88 old body crewcab dually.

The 1981 to 1991 one ton duallys ( and Suburbans) are the old square body style and chassis.

The wheel bearings in the front are the same. I checked.

Check www.rockauto.com check and see if the spindle part numbers are the same.

If they are, you are in business.

Some chassis stuff will interchange.

Just my .02

I just did a search at www.car-part.com. They make a distinction between "C" and "R" type trucks for '88. I get different hits depending on which I choose, so I suspect they are different.
