Is the rear suspension is interchangeable between Civic EF9 and CRX Si?

For example :
LCA of EF9 part is - 52350-SH3-A31 ARM COMP., R. RR. LOWER
LCA of ED9 part is - 52350-SH3-G11 ARM COMP., R. RR. LOWER

As you can see all the same except last three symbols, but is there a difference if not why part is different?

 

same parts.

 

It depends on exactly when it was manufactured actually, early versions had the US 88 LCA. My 89 JDM EF8 has a 88 USDM style LCA. I'd guess the EF9 would be the same way.

 

he didnt list the box style LCA. (specifically 52350-SH3-G03 R, or 52360-SH3-G03 L)

and if he's asking whether the shock from a 88 is interchangeable with a 89+ style LCA, then thats just a stupid question unless OP is blind.

 

I was just going off of the chance he didn't look at it to tell what exactly he has. I wanted to at least mention there is a possibility that both part numbers are wrong.
