do you go into the back underneath or loosen the whole dash panel from the front? Or both? o No: Thanks
buickperformance.com This site has some info. that might help. If you have small hands and are nimble fingers,you might be able to install the tach from the rear without removing the entire cluster. You will have to take your time and be patient. It will help also if the seat(s) are not in the car so you can lay down and see what you are doing. http://www.buickperformance.com/cluster.htm Good Luck Bert
