B16 intermediate shaft?

i have a Jdm B16A being swapped into my 90 crx si. it didnt come with the intermediate shaft, so i was wondering what one to use and where to get it. also, i have integ steering knuckle/brake assemblys i boought with the motor what intermediate shaft/axle combo do i use? is there anything extra i need for the larger brakes? another question i had was about O2 sensors; i know the B16 is supposed to have 2 and the d series has one; where does the second 02 sensor hook up?i am using the d series wire harness. ive heard that hasport has headers that have a second O2 bung in the appropriate place wondering if that was a good idea or DC sports?any help would be greatly appreciated thanks

you'd be fine using 90-93 integra axles with the mid-shaft. thats what i used on my swap. also, i had my friend make me a test pipe to fit in place of my cat and had him weld two bungs for o2 sensors. i remember reading somewhere that you only need one o2 sensor with this set up but i'm not sure if thats correct. if you have any further questions email me at [email protected].
i'd be glad to let you know what worked for me in my b16 swap.
