Is there a GM part number for this?? What year Summerset did they come on?? Can I get It aa Autozone?? Will it be Bosche?? I want to keep it original looking??I know these sound simple, but I want to get the right stuff...
Thanks--Paul
The part number is on http://www.gnttype.org in the Part Numbers section. It is a Bosch unit and it ends in "237" (hence the moniker). Stock GN/TR was "233".
You can get it for any year 3.0 (Sommerset Regal was the most common one) or the TTA might have it too. Before you spend $45 on it, you might want to consider throwing another $40 in the pot and getting an adjustable regulator from one of the vendors and being set for life.
FYI,
I just picked up a 237 regulator at, of all places, a foreign auto parts shop. It was kinda' crazy...but there was a sign stating they were a Bosch distributor and they had one in stock for $40.
Anyway...the Bosch PN is "0 280 160 237". The TTA's did have this regulator. I THINK the GM PN is 25523720.
I'm new to the TR scene, and decided to stick with a fixed pressure FPR until I get a scan tool and get a handle on tuning.
