rear disc brake conversion

i was just wondering if the 92-95 si's had the same identical rear discs as the del sol's, because i am about to purchase a rear disc conversion for my drums but one of the brakes is from an si and one is from a del sol. Any input regarding this would be appreciated.

they are all the same, just the e-brake cables are different.

so what cable do i use in order for the e-brake to work?

I have the same swap on my hatch. Make sure that you change the proportioning valve from a 4-front/1-rear, to the 4-front/3-rear from the del sol or your rear discs will pretty much be of no use.

You can use an e-brake cable from an integra or one off the civic si. The del sol's e-brake cable is too short.
