well as far as parts go, you'll need a 5-spd
tranny, clutch pedal, clutch cable, clutch assembly, new flywheel, and all the little etc parts...
how skilled are you as far as drilling, nut &bolt turning, and dropping a
tranny? if youve never done it before.. plan a week to do it.. most likely get it done in a weekend..but complications may arise.. its a lot of work.. and you have to go thru with it... a shop may do it quicker but they will charge you for their work.... so depends on if it sounds like a project you want to do or if you got the money for a headache-free install. as for trading.. it depends on how much you can find the same car for with the 5-spd in your area.
