1993 Bass Tracker Deck

[guitarplaya39]

Does anyone happen to know if the rear deck platform on a 1993 Bass Tracker is wood or aluminum? I want to mount a trolling bar and was planning on using lag bolts if it was wood (which I assumed) but I've seen some places online that said their front decks were wood and the rear are aluminum.
Asking on here because I haven't had a chance to tear up the carpet to check.

Thanks!
