I acquired this 88 wagon that has driver headlight area damage. The frame there is pushed towards the coolant reservoir. The headlight assembly won't sit flush, really knocked up on that side. I found an image on Google of the headlight frame part out of a crx, but Idk if you have to cut it out or is it simply bolted?

 

Spot welded

 

You will need to drill out the spot welds, and yes you can replace only that section.

 

It's called a bulkhead.
Some places call it a radiator support assembly.
Just so you know when you start looking around for one.

 

I actually have damage to the same area. Its been rigged enough by the previous owner to look correct on the exterior but has bugged me for years now. About a week ago I actually went to the JY and cut this section out of a donor car to repair mine properly in the spring prior to re-painting the car.

 

Is it easier to cut the section or drill out the spot welds? And I know that 88-89 and 90-91 have a lot of interchangeable parts but are the frames the same? Like a 90 wagon frame is the same size as the 88 in that area?

 

Spot weld drill bit - get several as they break easily.
You can check the part numbers for the different cars on
Majestic Honda - The Internet's #1 Honda Automotive Parts Store to see if they are the same.

 

Sedan and Hatchback and CRX front bulkheads are all different. I imagine the wagon versions are also different.

 

Well in the junkyard it's easier/quicker to cut it out. Of course on the actual repair job you want to do it at the spot welds

 

Battery powered sawzall to cut off more than you need, then you can spot weld drill to perfection at your leisure in your garage.

 

Bought a sawzall, bent like 5 blades but I cut the piece out. Now do I undo the spot welds on the piece I cut, then undo the spot welds on the car and just slip it on and find someone to re-spot weld the same spots?

 

Yes, although I'd advice starting with a a few tack welds and a full mock up before committing.

 

^^ or machine screws and then weld.

 

lol. So true. I made the mistake once on a prior JY run for a different project of only bringing one bade. Bent that one so bad it was ruined. After that I learned to always bring multiple blades.
