you can swap the lower control arms.

the geometry is completely identical. theres no real difference.

welcome to hondas.... this is basic info. you ought to start with reading the FAQ's.

 

As Tyson said, as long as you keep the '88 shock and rear lower control arm together they will fit the '91 CRX without issue.

 

thanks thats what i needed to know.
