12' clutch cover on 11' ?

[bluespark]

I took the metal clutch cover off my 11' 300 to replace the leaky POS plastic one on my 12' 300.

The plastic 12' cover has a molded nipple that hits the clutch push rod when I tried to fit it up to the 11'.

Can I grind off that nipple and still be able to use it back on the 12'?

I was going to try to slap it back together for some track time this weekend since the 12' is 3hrs away
