I went through this whole thing with my engine swap. I only wanted 2 gauges and I could only find triple pillars that were too much $$$ for me. I ended up buying a single pillar pod from Autometer for 3rd gen 4runner/Tacoma and shaping it with heat to fit. Then I trimmed off the excess and they fit perfect. I think the part number is 15411. Its the same pod that TRD uses for their boost gauge.
