A 78 hardtop on a 74 body - Help!

[Cherrick]

Has anyone done this?
I bought a hard top and ambulance doors from a 78 FJ40. I want to put it onto my 74. What is it going to take?

Also, if you know an outfit that can do this turn key and a really good job, please recommend them here.

did you search ? this has been covered on here many times and will require some rear body work to do it right
