Bagging a 1985 Cadillac Fleetwood Sedan?

I'm looking at possibly buying a 1985 Fleetwood sedan to bag. But I need to know what type of parts you need to bag it. Is it cups all the way around? Do I need to link it? What needs to be done to lay frame on 20s or 22's? I have a bagged s10, but I don't know anything about bagging a Cadillac.

I had an 84 coupe... I think it should be the same...  I had a regular bag set up...  It had 2600's all around, in the back we used bag plates off of 4 inch round pipe for the top and regular cups on the bottom....  the front we used cups.  I had the stock rims on and it pretty much layed out. The size of the tires would have been the same size as the 20's. I dont remember if we notched the rear, but the job took my friend 2 days.

Alright, what kinda cups did you get?  Because I can't find any cups for a Cadillac. 

i dont think anyone makes cups for the 80s caddys. but if anyone does it would be cool cars/CCE
