which distibutor do I have?

I'm going to have my intake plenum off to replace the fuel regulator that leaks and I remember my PLASTIC distributor body is stripped and needs removed so I thought I'd order the replacement.

Years ago when doing cap/rotor,plugs ect. I priced out only the plastic body and was less than $20 , but I didn't get it.

I now want to get a new distributor with cap,rotor,body,internals, ect. but Which one do I have?

It is a 1995 W engine with posts out the side (horizontal)
The body doesn't move and has a roll pin to keep it in place along with clamp.
It is called a high voltage switch I think and is early OBDII.

There's a number of horizontal posts on rock auto , but some have metal body and what is PM module? Do I have that? K-29?

I guess the link won't work 1995 / blazer / W / ignition /distributor.

1995 was a changeover year. They came with 3 different systems. Both of the later systems used horizontal connections for the spark plug wires. If you tell the parts store the wires are horizontal and that you have a camshaft position sensor in the distributor, or tell them it's a 1996, you'll be fine.

I was going to get from rock auto.

There's no question when getting a cap, but on the complete distributor it could be a

DORMAN Part # 690900 (could be plastic)
A-1 CARDONE Part # 301636 (could be plastic)
DELPHI Part # CZ20007 (looks like a metal housing)

I don't know if it has a cam sensor inside.

CARDONE SELECT Part # 841639
A-1 CARDONE Part # 301639
RICHPORTER Part # GM02

also looks promising from 1996 listing.

How many electrical connectors are on the distributor housing? If only one, it is a camshaft position sensor. If two, then it does NOT have a CMP sensor. If the distributor is not adjustable, like you mentioned, I'll bet is has one connector. ;) 1639 distributor number.

I just looked at it.

It has at least 2 connections that I could see.

A 3 wire pointing back and then a bit lower and to the side it has a smaller 2+ wire connector.

I'm not sure if this helps identify it , but I remember the housing being able to be used for a 6 cyl or an 8 cyl engine. If you had an 8 then the rotor points to the 8 and the 6 cyl points to the 6 (maybe it was inside the housing) under the cap.

If the distributor looks like this, it's the old style OBDI distributor, part # 30-1635

Probably be a good idea to bring the old distributor with you to the parts store and match it up.

definately not that one. It has two connectors, but only one is pointing back , the other is to the side and lower. With a black plastic body.

These are it, I don't know where I got two connectors from, it is only one.
