a few 4 speed conversion problems

It's been a while folks. swapping a 4 speed into a small block 68 barracuda. A few mysteries are popping up. Answer as many as u can stand. 1)I decided to do a mock up fitting, so I installed bellhousing, empty trans case, & crossmember. This allowed me to locate where Hurst comp plus comes up thru floor and cut that spot out. When I dummy fit the AMD 4 speed hump by just feeling how it conforms to the floor, it seems the shifter is too far rearward in the hump hole. It is literally touching the back lip of the opening and rear adjustment lock bolt touches hump as well. This can't be right! Could summit have sent me the wrong hump? Could motor be installed too far rearward? 2) Another question pertains to the shifter rods. Which direction do the 90 degree bends on rods go when installed in shifter mechanism arms?? Towards passenger or drivers side or a mix of both. 3)And finally, which arms on shifter mechanism are which. I heard long one is Reverse. What about other two?
Thanks much, Neal
