Weber to FJ60 air cleaner adaptor
This looks like a Redline Weber 99010.302 adaptor. Man-A-Fre actually has a very good price (99010.302K), and it looks like they even tapped it with a bronze beaded step for accommodating a small air hose from a PCV valve or 2F distributor cap breather.

The 2F I'm installing came with a Weber DGV 32/36 carb with this adaptor between it and the stock air cleaner, which contained a dry paper filter element. All in all that seems like a decent Weber and air cleaner solution the PO went for (except it should have been a 38 DGAS), better than an aftermarket design involving an open filter (like these default air cleaners that ship in Weber kits). I'll try putting all those bits on the Weber 38 in my 1975 FJ40.
For now the set up on the 2F has to go as the FJ60 air cleaner does not fit under the early FJ55 hood ergo this fooling around with the rectangular air cleaner which sits on top of the carb that Redline Weber provides in their kits (you'd think there would be enough market demand such that WIX would make a filter for it...).
The dead F motor has a Weber DGV 32/36 as well; that's where I got this rectangular air cleaner housing from, which actually seems like a decent minimalist open filter design (the air cleaner "housing", not the carb) but, please, a paper filter element.
I have to wonder if the dead F's old gauze-in-metal-mesh filter element with areas of blown out gauze didn't help contribute to the engine's demise.
P.S. Here's some verbiage from Redline about the 38 versus 32/36 choice:
http://www.redlineweber.com/html/Types/making_the_right_choice.htm
"Designed for engines displacing 1200cc-2300cc, the DGV Series carbs feature diaphragm type accelerator pump circuits and models with manual, water or electric choke actuation. The DGV also has a power valve circuit to facilitate low vacuum running conditions."

"The 38mm DGAS carb should be the only consideration if the engine is in the future or currently going to have any level of additional engine modification. Such as headers, free flowing exhaust, a cam, or rebuilt engine. Usually these motors will be improved over stock with oversize pistons and towing cam. The 38 will enhance the improvements of any of these items. The 6 cylinder engine applications are particularly enhanced by this application. In-fact on ALL JEEP and LAND CRUSER applications with any upgrades this is a mandatory choice. Other wise the progressive will require extensive re-calibration to work properly. "
