4040 prop valve vs 3040/3030

Hey guys! New to the forum (: I’m currently doing the “quick” and easy abs-delete on my GS. Unfortunately, someone has torn out all the 4040’s in junkyards across Portland. Plenty of 3040’s and 3030’s are available though, and I’m just curious as to how big of a difference it would make to use one over he 4040? What if I used an adjustable prop setup?

I dont think your brakes would work very good. I hink that our integras have bigger master cylinders and thats probably why we have to use the 4040. Just order a used one
On ebay or buy a new one

I just ordered mine yesterday because old one started leaking.

Btw there is a guy on here selling one for 25 which is a great price
