According to Chuck the 78 was the first year for the support strut. I have one on my np203 - th350 78 k5. I replaced the Np203 with a NP205-th350. I'm still working out the support strut as it does not fit with the np205 swap.. it is to short.

I have the frame mount for a 72 but it falls short on the 78 frame. According to Chuck the frame was changes this year.
I'm still looking for a good solution to supporting the np205 in the 78 k5.
