Shown here is our BRAND NEW REPRODUCTION Double Groove Pulley for all cars that have no air conditioning but WITH power steering. We make these from heavy duty steel, just like the originals. These have one pulley bolt hole elongated so they'll fit on the '72 and later symmetrical bolt pattern, AND the earlier offset pattern! Diameter is about 6 1/2 for groove 1(water pump and alternator drive groove) and about 7 1/2" for groove 2 (power steering drive groove.) Offset is 2" on groove 1, and 2 and 13/16" on groove 2. Use on all engines, (even small blocks!) Forget about scrounging up used and often damaged originals... we've got great quality brand new reproductions at practically swap meet prices!
