I was told if I bought 1990 integra axles they would fit in my 89 civic w/ b16a1. I bought some today at Autozone and the end at the wheel hub is to big to fit. What do I do?I have 1989 civic std w/ a b16a1

you need to swap your knuckles/hubs for ones from 88-91 CRX/Civic DX or Si - if you want larger brakes, use the 88-91 Civic EX knuckles/hubs

yep swap over the hubs and they will fit, the hubs on your car now are 23 spline. you need 26 spline.
