Possible 73 L48 Water Pump Casting No.'s

Re: Possible 73 L48 Water Pump Casting No.'s

Any dated part that was unique to '73 or was introduced for the '73 model year. For example, we've pretty much given up on finding a 3997770 or 3997771 intake manifold. The number of those cast prior to 8/1/72 is a very, very small number. We still hold some hope of finding a 7043203 carb that is date correct but the chances are we'll never find one. For parts that carried over from '72 - no problem. One of the biggest problems is the low value of these parts. Not many people want to lug around a 40 lb intake for a $20 sale. Finding a good rebuildable 7029215 carb core isn't easy but there is a lot of incentive to anyone who finds one to put some effort into selling it.

I had the opposite problem given the late build of my car.

Yeah, '69 is a year that suffered many changes during the production year. There are some parts that changed 2 and even 3 times. For example a set of early design '69 bright blue (411) seat belts was really hard to find and really, really expensive to acquire. But I suppose it's these challenges that keep the hobby "interesting."
