Triumph TR6 - Need a measurement please!

With regards to previous thread on overdrive failing, I tried to check the trans fluid, but the previous owner had fit a fibreglass trans tunnel in the car and I can't get at the plug from the drivers foot well. Can someone please tell me how far back from the firewall and how how up from the floorpan the centre of the plug is located? I plan to drill a hole trough the fibreglass so that I can get at the plug from the drivers side, as I dont have a hoist to get under the car.
Anyone have any wiser suggestions before I start drilling?
Thanks much

Thanks Guys,
If you look closely at the drain nut on the transmission you'll see I had a 3/4" nut welded sure is easier to work with it now...I plan on doing the same to the diff drain plug.

Better still, has anyone found a NPT "Allen head" plug?

I went to Carquest and picked up a brass plug with a square head that a standard socket will fit. Take the old plug with you and they will match it up.
