I have a 68 mustang coupe with a 289. i have factory AC vents in the dash but thats it (the previous owner pulled the rest of the AC system out for some odd reason). I rode around all last summer with no AC AND the Vinyl seats in the hot Southern Cali sun and i dont plan on doing it again this summer. so how much would it cost to get the rest of the system? is it difficult to install? if so how much should i expect to pay to have it installed? I have seen the daily driver AC kit that bolts under the dash for around $800 i think would this be a better deal? i would like to stay with the in-dash setup but i might be better of going the other route. any help?
