66 under bench questions- tire jack and sound

[msg]

I removed everything from the cab to restore it and now Im looking into adding some speakers under the bench vs the tire jack. The tire jack that was in my truck looks like its damaged anyway and I would need to both find a replacement and possibly relocate it. Ive got the gas tank in the cab so I wouldnt have a bunch of room.

If I add the sound system I am thinking under the bench I would need to find a place for my replacement jack I think. The speaker system is the custom auto sound under cover II that has two speaker boxes at 11"W x 12.5"D x 3"H.

Anyone dealt with this and found a good tire jack replacement and location?.
