Re: CJ t-case on FSJ transmission
Yes, the D300 will bolt up to a 727 from a FSJ. However, there are clearance issues with the front driveshaft on the passenger side clearing the 727 housing. Do a search on here and you can get lots more info. Some people say that a 4" spring lift will allow the necessary clearance.
You could also use a part time case out of a FSJ such as a NP208 with a pair of axles from a FSJ with front drivers side drop. On 1980s FS Wagoneers and Cherokees with part time transfer cases they will have a Dana 44 front and AMC20HD or Dana44 rear
