Default 1970 GP rally gauges
I have a 70' Grand Prix I would like to install factory rally gauges in. What years interchange, and will GTO gauges work as well?

1969 to early 1972 (without seat belt warning & 120 speedo). GP gauges only if you want the correct "green" backlight. GTO will physically fit, but backlight is white.

What is the fitment issue with the 1972 gauges with seat belt warning?
