So I have a 1998 Acura integra and I accidentally broke 3 lug nuts and where I live nobody had a knuckle for me to buy so I can swap it so I was wondering if a 1995 Acura integra knuckle can fit in replacement for it

 

It would probably be easier to just replace the studs. Hammer out the old ones and feed the new ones in. As long as they are the oem size it should be an easy install.

 

I can’t because behind the studs there a little lip that prevents me from replacing them unless I cut a grove into the knuckle but idk what do you recommend

 

A 95 will bolt up, but it may or may not have abs sensor and wire mounting points, if you aren’t abs (i doubt it) then not a concern.

 

Some 95 models do have ABS, don't ask me how I know.

 

Why not just replace the studs and the wheel bearing? A new Timken wheel bearing and lug studs is like $50 on rockauto. Beat the hub out of the knuckle with a big hammer, beat the wheel bearing out, take it to a shop and have them press in a new bearing, press in the studs, then press the hub back in.
