This part was what I needed to get back on the road. A lot of the after market parts do not include the bolt and spacer. That’s fine if your old parts are all ok, but if the bearing failed, you are probably going to need the spacer. My old spacer was badly damaged when the bearing failed (at 247,000 miles). But this part had everything I needed to fix it. Installation was easy, and it fit perfectly. Highly recommended.

The amazon fitment tool says this part does not fit my Chevrolet 1500 88-98 V6 4.3L in spite of GM fitment tool showing this as an exact match. Glad I double checked.

Replaced the old one on my 1989 Suburban. It was the correct setup for a V1500 Suburban with A/C. If you replace the belt, check lengths. Mine is shorter than the actual belt for a Suburban with A/C (according to parts stores). My assumption is because mine does not have the smog pump, which would require extra length.
