Hello!

First time poster, long time lurker. My question is about the bumper support assembly for the CRX Si 88-89 vs 90-91. The beam and the support look exactly the same across all four years to me, albeit slightly different part numbers. My question for the forum is... are there any differences I should be aware of?

The parts in question are circled in red...

 

I think you will be fine. I can't confirm from personal experience, but I do have a 90-91 cover and beam on the rear of my 89.

 

this was the top google hit...

Also part number 10 in the diagram there... is that for the Si or for the HF?
