This is where mine is right now with longtubes. I don't know what I was thinking at the time, I should have put it in the header collector before the flange but in any case it seems to work fine. I did not have to add any wire to the sensor to reach this location either, just removed the tape from the harness and pulled out some extra, though that is an aftermarket sensor with a longer lead.

I did replace the sensor when I swapped headers.... i believe a bosch part. But there was no need for any extension.
FWIW... my headers are FlowTech.

I used a Magnaflow 400 cell 3" in/out cat for my replacement. The P/N is visible on the underside of the piece. I also re-used (I just cut it off with a rotary wheel) the secondary air line and had that added to the Y-pipe I had built. Passed visual inspection in CA, NV and WA...along with the sniffer.
All in total, I paid just over $300 for my custom y-pipe, Magnaflow Cat (that thing was $100), O2 bung and air return installation, and 3" single side exit Flowmaster 40. Installed.
I drove the truck with open headers and no exhaust (after I installed the headers-only about a 2 mile drive) down to the exhaust shop for this work. Took the guy about 3 hours to finish up. Been on the truck since 2007 and about 60,000 miles. Not one burp or issue later.

When I get my E4OD tuning right, I will opt for a longer more efficient sound deadening muffler and sh1tcan the 40 series. It gets loud. Right now, the motor won't hit much of anything past 4000 rpms with the way this transmission shifts. On the dyno, the motor pulls well past 5,500 rpms. When my shift points for 1-2 are dialed in the higher rpm's, the flowmaster 40 will likely be replaced with something quieter.

well i have to keep in mind u have a built 302. i had a stock bronco except for summit shorties magnaflo cats and the 40. i wasnt happy with it at all...my truck now is a 5.8. its pretty much stock and will stay that way for now except for a new cat and muffler...now y did u spend that money and only go to a 306? y not a 347?

The extra displacement would be nice in hindsight, but the truck scoots very well as is with the power upgrades and 4.10's. If I could only keep it in gear longer through 1st and 2nd gear without the lazy 2500 rpm shifts, I'd be happy as pie.
Truck gets a legitimate 16 mpg's as well. Even turning 33" tires and with 4.10 gears.

It was a very cheap build that way. I spent just over a grand in machine work and parts. The only real money I spent was on the head work. I don't think a 347 would run as well as this 306 using stock ford EFI/MAF junk, and stock Ford PCM. And I still haven't been sold or bit the bullet on a tuning solution for this motor and trans. combination.
