Yup........

With small micro air saber saw the front broken pipes, with fine blade, and insert replacement fabricated units inside to be RTV'd, epoxied/plastic welded, and or clamped.

No dash to take out.

If can't ........dissection it is.

fabricated units lol this is gonna be fun and kinda the direction i was thinking. should i use copper, brass or plastic thats where im stuck.
