got a ls1 guage question for yall.

[jdmathes074]

i am currently in the process of getting all the parts together to do an ls1 install on my 86. ive seen somewhere that someone used guages out of a 90-91 model suburban but i cant find it anymore. im trying to not spend the money on the dakota digital guages. any helpful information (if its possible, worth it, part numbers, etc.) would be greatly appreciated.
