"My headlights are a bit floppy on the outer edge, meaning if you push on

"One answer I can't find in the archives:  Will the square E-codes fit
into the stock square buckets and grill of an 86-91?  Projektzwo is too
expensive for me, and I think I prefer to remain rectangular . . ."

I'm not positive but believe these lights fit right into the stock van
square buckets. Leave a question for David Marshall at the below link.

Not cheap by any means but apparently very effective. The headlight adjuster
kit is on this same page as well.
