He also has a 29 coupe with a 216 and T5. The rear in it is a 55-59 (62?) 3.90 third member swapped into a 39 truck housing with solid perches welded on in the right spot (running the 39 axles). I am wondering if your 36 axle housing would accept the 55-62 third member in the same way, ensuring a good fit, and if the axles would work as well.
The '36 is an enclosed torque tube driveline and rear end, so it has to go when the T5 is swapped in. And if I am not mistaken, you cannot even change gear ratios in these old differentials.
