what parts interchange ?
 

i got a 94 civic ex with 1.6 5 spd disc brakes on rear , i need a wheel bearing replaced , so i went to local junk yard , but all civic with disc brakes are gone .my question is , what parts will interchange with my 94 , i need the whole spindle .found plenty of accords and acura with disc brakes ,but not sure they will fit . and is there information about all interchanges , also what is the different in a ex, dx and si . thanks for any infomation someone may help me with .

I believe integra trailing arms are the same as civic trailing arms.

As far as the trim levels, it's all in the engine/options.

Generally, SI > EX > LX/DX/CX

SI's and EX's have the best engines and usually have the most options standard; my old '94 EX had literally every option available for USDM civics as well as the best USDM civic engine in '94.
