transmission length

[m347]

Anyone know the difference in length of a c4 and an FMX transmission? Looking to change from FMX to c4 in a 1970 Mustang and want to know if I will need a longer driveshaft.

Here's what I came up with....

Thanks. Not much about the FMX online and I have not pulled it out yet. Waiting until I find a good c4. The FMX still works good but no one makes a good shifter for it. Thought about trying to make something up like this.

Anyone on here ever try this?
