Will ck what finish my late '72 T/A's sending unit is.
Was 6463727 the INTROL version, I've forgotten?
Years ago I parted out a rusty April or May of '73 built LeMans GT with factory guages & have the oil filter adapter with original sending unit on it, In hauling boxed parts over, so have yet to run across the box of oil filer adaptors but know I have that box.
