the link doesn't work, but you can use the 88-up headers on the 87.

I was told that the 88+ headers would work but the frame would need trimming.

you can run o2's with the old style headers, just have the o2 bungs inserted in the exhaust pipe just after the collector... Also, your truck isn't too low for Long Tubes, so that's what I would run...

i remember reading somewhere though, that the o2 sensor had to be within 12" of the flange so it could get hot enough to get an accurate reading with the computer......if that is true, than putting the o2 sensor in the collector would be too far, and the sensor couldnt get hot enough, right?

i just remember reading that somewhere.....

First off on the heated sensors, any parts store should carry them. They come in 3 varieties: 2 wire (good), 3 wire (better) and 4 wire (best).
The 2 wire would be the easiest to hook up. One wire is the signal and the other is the + for the heating element. That one would simply go to a power source that's hot with the key in the run position. The 3 wire sensor adds a ground for the heating element, and the 4 wire adds a signal ground. The 2 wire ones just ground both through the sensor body.

As for the '86, we all missed the carnige on the pass. side. That little rust hole on the drivers side was nothing. Here's where it stood as of day before yesterday. 86 Progress Pics I've since got the spring hanger bolted back on and moved to the driver side. I hope to have it ready to bolt the bed back on tomorrow.

I had the o2's from my wagon just tapped into the pipe about 3 inches after my collector flange. Worked great.

I should have a few more ready for ya this evening. The passenger side is completely back together except for the gas tank, and I just finished welding the repair panel into the driver side. I'm in taking a break now, and then I'm going to go back out and grind the welds smooth and slap on a coat of POR 15.
I hope to have the gas tank back in and the bed ready to go on this evening.
