JARRO Thanks man, I knew SOMEONE would tell me the truth! haha

Bouncy---- I have no clue. Expand on what you are saying and I will go look. I am 90% sure I have an OE 2WD frame, but am not sure what you are asking. I will assume that the answer is yes, cause I can get my hand behind the dizzy, and there is about 4" between the radiator, and the water pump

Here is a pick of a GM connector used in those bulkheads. Also used in old style quick disconnect wires from the 60's and early 70's. I bought these in bulk from GM years ago, but I've also seen them available in various parts stores if you look around enough.



Looking at that closely, you can see the top portion of the connector is not attached. If you simply squeeze the top and bottom portion together with a pair of needle nose plyers,,,then push on the connector and the wire will pop right out of the bulkhead.

When you pull the bulkhead from the firewall you will see a bunch of these connectors staring at you. Just squeeze and push the one you want to remove from the backside, and the wire will pop out of the bulkhead from the front side. Very simple.
Once you have your new wire made, just simply push it back into the bulkhead until it snaps into place, plug the bulkhead in and you are done.

Sorry I don't have detailed picks but this shot of the connector should give you an idea of what you are dealing with. I'm sure once you dig in you'll find it's pretty self explainatory. Hope this helps.

Edit: No special tools required.

All by myself I figured it out!!! I got up out of my chair, and raised the hood on my Blazer. looks like there is three holes for the motor mount stands. Mine are in the first two ( closest to the rad ) I will bet there is 4-6 inches behind the dizzy

Great info, thanks for taking the time explain it to me, very good job! I may dig around to see if I can find a connector to try it out...I have seen those before, but never knew what thet were for

Thats why you have clearance. On the 4X4, the engine is mounted further back, and the valve cover and hei get real close to the firewall.
