This is what I'm stuck on right now with my swap, can you give me some details? To make things more complicated on myself I decided to swap a 1998 dash into my 1991 to go along with the LS3/TR6060 swap so I piicked up the sender and pigtail from a 1998 and was going to try to wire that in but the LS3 sender is bigger than the truck one so I started looking for an adapter, from what I found I believe I need a M16x1.5 to M12x1.5 but can't find one.

Appreciate any info you can give me, also picked up the 3 wire coolant temp sensor and pigtail so gonna tackle that today.
