Gm 3800 3.8l Upper Intake And Plenum 3.8 Repair Kit

I purchased that replacement kit for the GM 3.8 motor. I thought it would be complicated to replace since I'm not officially a mechanic, but it took me about 3 hours to replace it on my 98 Park Ave. Now to replace the one in my 95 Park Ave.

Where did you get the kit? I live near Philadelphia but I haven't been able to find someone who carries it.

Napa/Dorman, easy to get.
