New to owning a Z. Previous owner had the car for about 10 years, and didn't do a ton of maintenance. Like change trans, diff fluids. I got done with the trans and went to do the rear end.
Its a 73 240z.
Male square headed bolt is the fill plug. I torched it, penetrating fluid. Torched it more. The only thing that I can get on there is a standard adjustable crescent wrench.
Is there a better tool? Do I need to remove the rear crossmember to have better access to it? If so, does anyone have a good step by step with pictures or a video on how to drop the crossbeam?
What about filling through the breather? Is that a check valve / one way valve? Or is it an empty tube? I took the cap off and am fairly certain I felt something inside of it that would make filling through it tough.
Anyways, please help before I round the head of this bolt off.
I don't have a welder, by the way... so if I need to weld something to it to get a better grip, it's not the best option for me at this time.
Thanks!!
