At 236K and change my VP died. I guess that's not to bad for the original stock pump. Got one ordered from Blue Chip and supposed to be in on Thursday.

I finaly got around to replacing the alternator with a new Nippondenso from Rockauto. The connections are the same but just a few degrees differance in relation to the field plug on the Bosch was about 2 o'clock and the Nippondenso is approx. at 4 o'clock. Everything fits just fine. DCV are now 14.4 and the ACV is indicating about 0.01 to 0.02. So far not having any TC lock/unlock issues.

Geno''s has oem style replacement headlights at a reasonable price. www.genosgarage.com

I adjusted the valves at 170K miles and reused the valve cover gasket. But ahead of time I ordered a gasket from Geno's for just in case for a third of the price that the local auto parts wanted.

Thanks. After looking at the pics of alternators on the Napa website, most of the connections look to be the same other than the back side of two alternators are a little bit differantly made.The reason I am wanting to check out the alternator is after reading anouther thread about the TC lock/unlock issue that I get from time to time.

Is there a differance between the Bosch & Nippondenso alternators as far as the electrical hook ups? I will soon be bench testing the alternator and replacing if needed with a new one. For what I have seen online is that only Nippondenso alternators are available new. All the Bosch alternators are rebuilt units. From what I can tell, I currently have an Bosch alternator (stock) in my truck Any input on this would be helpfull.
