Thanks dude...what about my axle problem

 

I believe all 88-91 civic axles fit into all 88-91 d-series transmissions. The inner CV joints should all be the same. The only fitment issues are at the wheel end of the axles. The CRX Hf and the Civic STD hatchback used a smaller hub with fewer splines.

Whatever axles you've been using on your car, *should* plug right into the Si transmission.

 

where did the axles not fit, at the transmission side or the hub side?

 

At the tranny it's supposed to be snug right up to the tranny but there's like half a inch gap

 

Are you sure they are "snapping" into place? You may not be pushing hard enough - it can be a pain sometimes. Don't beat on the boot to help it go in, or you will cause a break in the rubber.
