XJ Bucket seat hardware question

[MrFreeze5]

Does anyone know what size bolts are needed to replace the rivets when using XJ seats with MJ seat brackets? Ive got a set of 2dr XJ seats to put in, but Id like to go get the hardware before I tear my existing seat apart. Thanks!!

I used 5/16" bolts. Seems to be working OK.

That did the trick. Thanks!!
