Here is the alloy brackets and pulleys that are for 95-98 Chevrolet, GMC C/K trucks and suv, and 98-05 4.3L V6.  These will fit 4.3L V6, 5.0 V8 and 5.7L V8.  These will not fit any 454.  These are good to put on the older V8 SBC and convert everything to a newer set up and get rid of the older V-belts.  Just make sure your old engine has tapped heads in the front for the accersories.  I know some old 60's heads are not tapped.  You will run 95-98 C/K truck water pump, power steering, A/C and alternator.  No cracks or breaks in these.  They are straight off the truck and is greasy and dirty.  Check out the pics good and make sure these are exactly what you need before you buy them.  They are sold as is, all sales are final.  No returns.  These are from a 98 truck.
