Damage under driver floor pan?

[Stupidfast]

Found this when removing the driver side lower firewall and floorpan. A 4 speed was installed by the PO, was this done for that?

what does the transmission tunnel cover look like? Are the front and rear door jambs on your tub parallel, or spread apart? Those may be telltale signs.

Need more explanation as to "what wad done" as don't know what you did and what the prior owner did.

On 4 speeds, the clutch lever is typically on the passenger's (right-hand) side. Perhaps this is why.

Looks like your standard after market access panel to me.

how long have you had the rig. Those cuts look fresh (no rust) enough that the PO should be able to remember what he had in mind when he cut it.
