I notice that the part numbers of '88 front suspension knuckles for the CRX & Civic are different for the same parts for the '89 and later cars. What's the difference, and can you use tha later knuckles/hubs on the '88 without having to swap other stuff?

 

I wouldn't know of any differnce in the knuckles for either year, they look the same to me. That's odd...

 

Only HF CRX and STD civic have different knuckles
