well, there' s a member here named Jester who can help you with rims. What type of parts are you looking for? Did you want to bag it, or hydro it? What are your plans so far?
Where do you live? You could put alot of rim sizes on it, from 13' s up to 22' s. You my be able to go bigger but I would stick to like a 17 or 18 with some sidewall if you want to do hydros. There are lots of pics in the gallery to look at for wheels idea.
i live in greenriver wyoming, and i would really like to do 20' s, would that work, also i want to know where there is a place that i can get some work done to it, i have been lookin on the net and i cant find any sites for buying aftermarket things for my ride
Your not gonna find a hydro kit just for a caddy. Your gonna have to buy it and install it into the car. You can try places like pro hopper, or CCE, or showtime... Best bet is to get a lowrider mag. and look for links there. Did you want to have the work done or install it yourself? If you have any skills it pretty easy to do.
