Bolts size for tranny line going into radiator r for a 68 gto? Gotta temporarily plug them

[Mr Twister]

Is it a 1/4 npt inverted flare? If so those are available as plugs

[rolling money pits]

You need a male 5/16” inverted flare plug, 5/16 being the line size, not thread.

Any parts store should have it if not HD/ Lowe’s and the like.

Thanks guys

If you can’t find a plug , I just weld the hole closed on the flare nut.

Yup 5/16”.

I am checking the gasket on the exhaust manifold and didn’t want tranny fluid coming out radiator when I disconnect the tranny cooling line. But I noticed someone before me swapped out the original cooling lines with after market ones.
