If I had an OE system... I'd update the condenser and keep the rest... you just give up so many features... if it was seldom driven and the clean firewall was important tho....

You may know this already, but a condenser designed for R12 will be very inefficient with R134a. The hoses will need to be upgraded too. The rest of the system will do just fine.
