Does anybody sell these? Just picked up some Watson headers.

I think I may uave an extra or have enough stuff to make one. I have Watsons also. 1 7/8" primaries.

I've built several for ppl over the years, with NO problems. (That and the little crooked dipstick brackets too.)

All it takes is the ability to solder and some braided hookup wire, shrink boots, and maybe some insulation tape.

ALSO! I highly recommend purchasing a couple bungs (Summit Racing) and welding the bungs to the outboard side of the header collectors. That will greatly help when you need to temporarily install the wideband O2 sensor (dyno turning, etc.) or when you need to replace them; accessing them can be done without even lifting the car, in fact!

Note: A long time ago, some idiot started a rumor that because the O2s are a "high impedance" device - which they are - and because of that, extending the O2 sensor wire leads would introduce too much resistance, causing problems. That bit of misinformation has been repeated 100s of times. Total BS.

Think about it: Adding say 0.01 ohms of wire to 1,000,000+ ohms or so imposed by the O2 crystal, not to mention the 3-4 feet of existing wire running to the ECM, is practically NOTHING to the O2 circuit...UNLESS someone botches the soldering job, or used aluminum wire to which solder will not stick..., etc.)
