Just got done installing the T and senders. I removed the vdo sender which was installed by the last guy. Turns out it had the 1/8" npt fitting. He also used a brass adaptor for it. So I removed his adaptor and threaded in my brass T (bought on Amazon) that has two female 1/4" npt holes and one 1/4" male npt end. Screwed in my new bwd sender, new vdo sender, got tired and went inside. For access to the nut on the vdo sender (the one that was already there) I removed the lower radiator hose and turbo shield j bracket. That also gave me more room to install the new parts. Will button everything up tomorrow. Hoping (a) no oil leaks (b) working vdo oil pressure gauge and (c) working oil pressure light.
