4th gen prelude calipers

i have a 1990 accord and i came across on a deal to get the lowering springs from a 4th gen prelude. they guy also decided to throw in the rear spindals so that i can do my rear disc conversion. now that i'm going to have the prelude rear brakes on my car, it would be nice if i could upgrade my front caliper's to the prelude specs, preferable from off a prelude. my question is do any of you know what kind of calipers are on the front of the prelude...1 or 2 piston? my car currently has 1 piston front calipers and if the prelude also comes with 1 piston, then there is no need for me to switch. thank you for your help in advance.
