Installing a Toploader in a Fox

[93stang351w]

i have a toploader and i just put it in and bolted it up to the engine.....the tranny mount is too far in front of the crossmember to bolt up...the motor mounts are bolted up ,so i cant move the engine and the tranny back to bolt up to the crossmember, all i need to move it back is about 1".....many people have done this toploader swap and it is sopposed to fit, but i dont know why its not fitting for me, i have the right bellhousing and everything else....any ideas on what i should do??? has anyone done this?? need help
