Catch a ride on the "way back machine" to 1988 and buy a GOOD 20 year old 68 Roadrunner, 383, 4 speed, 3:54 gears for $1000-1500 and you will know the answer.
Down here around Houston and such, ALL auto upholstry shops are Hispanic and charge like brain surgeons. I had my 62 Lancer's oem rad recored about 10 years ago when I bought it. Never used.
