wow, thats nice. i second everyones opinion here, at minimum you should replace the brake hoses and fuel lines. prolly replace the coolant hoses too.

i just did the water hoses on my 109 3.5, it wasnt as hard as i thought it was going to be (i also did the water pump, intake gaskets and seals, and the injector seals), the car runs much much better, and it was seeping coolant from ALL of the old hoses. that whole job i'd say is about a 4/10, with an oil change being a 1 and a full resto/engine efi hot rodding swap at a 10.
