finally swapping over to an ls6 intake- bought one off a guy on here, gatta order gaskets, coolant crossover pipe, and the rear coolant plugs
gaskets arent a problem, and i found a coolant line "kit" for $60 shipped,
but on gm parts direct i found the crossover pipe for 32, but cant seem to find the plugs, anyone go the part number? i think it might be 12553191?

Correct P/N for the rear plugs is 12602540

They go for $6.64 each through sdparts.com

I've heard shipping through gmpartsdirect is outrageous, so you might want to look elsewhere

I bought my crossover and rear plugs from sdparts for $57.08 shipped

 

1 of these. Coolant Pipe #12581213
2 of these. Coolant Plug #12570678

 

While correct those are old part numbers that have been superseded, I just ordered new lines a couple months ago and had to track down the new part numbers.

12570678 superseded by 12602540
12581213 superseded by 12602544

 

ahh thanks I will write those down in my book

 

just the info i was looking for thank you!!!
