69 Z/28 Water Pump Pulley Real or Repro
« on: Today at 01:49:37 PM »
I found other threads about this but no overall guidelines about real vs. repopped pulleys.
I wanted to get you guys opinion on this pulley:






I thought the font looked good but I'm questioning the welds that retain the inner support.  I have noticed on crank pulleys that the welds on repops are on the flat face (like above), but on originals they seem to be on the side around the circumference of the mounting flange.  Is that correct and does that also apply to water pump pulleys?

Any feedback appreciated!

My original is welded inside of the pulley, spot welds through the support cup and the outside minor diameter. The one shown above is a reproduction, but a good one - I've seen similar from PartsPlace and other vendors that look like this.

Considering prices for OEM's are usually through the roof, ones like this are usable until you can locate a used OEM or NOS - my opinion -
