Bolt size for drivers seat

[Hogsters]

I’m trying too raise the drivers seat in my 2016 Ram approximately 1 1/2” but can’t seem to figure out what size the bolt head is. Does anybody know the size, I’ve tried 11/16 and it’s to small and 3/4 and it’s to big.

18mm

15mm for the front bolts and 18 mm for the rear bolts

Soak the treads with penatrating oil, maybe hit the nut plate under the cab with some propane heat, just not alot of heat.
Interior fire would really suck.

Thanks for all the replies! I pick an 18mm socket tomorrow and try the ”tips” if the bolt is giving a hard time.

I snapped a rear mount bolt (18MM) on my 16. SOAK THEM !!!!!
