do the 12
it will cost more for r12,repair and supply,but you will maintain the r12 comfort you are acustom to. R134 WILL NOT:
1-be Cold in city driving
2-get very Cold during highway driving
1-leak thru your hoses
2-make you sorry you converted to R134.
of course,if you don't have much of a summer this may not matter to you. here in Fl. i like the almost pain R12 cold gives you when you put your hand on the the ducts.
