floor shifter cut out..

Ok, I am cutting a hole in the tranny tunnel for mounting my floor shifter. Its a stock top loader shifter out of a 69 mustang. Is there any way to tell where to cut the hole other than putting the shifter in and cutting where needed. There are no markings other than two little dimples that may suggest where it goes. These dimples do not look like they are anywhere near where I need to cut. I will try and draw a diagram of where they are. Its not much of any image! ..but it should give someone that is familiar with them an idea of what I am talking about. I really have to apologize for this drawing!! Anyway...are they any kind of reference point for what I am trying to do. Also, is a 200 I6 with a 3spd floor shifter in the same location as mine will be? I may have a vehicle that I can look at if it is.

Thanks in advance.

I dont know about the dimples but the 3spd and 4 spd did come out in the same location for me.

 

I don't know how accurate this would be, but the factory insulation under the carpet is perforated in the location of the cut-out. It might be of some guidance.

 

jim, when i mounted my hump for the stock auto floor shifter it would only set on the hump in one place .as dab, said the pad lined up with that location also. with me the fear was being cutting the hole to big. i under cut it and then made it bigger. you are working with metal so it really can't be too big for long. not as long as you have a frig., washer or dryer around. he! he! remember, measure twice and cut 3 or 4 times.he! he!...frank...:bananaman :bananaman L.T.N.G.

 

I will check on the floor padding and see if has the perforations. Thanks for the advice guys.

 

My car has the dimples too. I thought maybe they are there for an auto shifter? That was just a guess. When I put my 5spd in, I measured from the bellhousing back to where I needed to cut the hole (I got the dimensions off the tranny) then cut a small hole. Then the tranny could be put into place and the hole opened up to the desired size. Good luck.

 

No perf in the padding...oh well, just have to guess!! Guessing didnt work to well for installing the small rear bumper holes.... I have an extra set of holes for an offset bumper if I ever need them. Measure, measure, measure...then check it again. Thanks again for the help.
