I'm writing a little article for it... I have pictures to prove it too- comparisons between my CRX shocks and the 89 Accord shocks that I have. I actually have the set of Accord shocks for sale (brand new KYB GR-2, never used) if you want them.
I don't know if you can use Accord shocks in the back- but the front is where the travel problem is, not the back.
Do be aware that the spring perches will be in different locations relative to stock when you mount the 89 Accord shocks, so if you use standard lowering springs, it's going to sit funny.
