Clunking on Downshift

Hey Guys,

My 72 Fastback makes a loud clunking noise when downshifting from 3rd to 2nd. Doesn't do it from 2nd into 1st.

The guy I bought it off put a shift kit in it so it has reasonably hard shifts, but shifts well up and down except for the clunk when going down into second on deceleration.

I was just wondering if anyone would have an Idea what this could be before I take have to take it into the shop?

Thanks in advance for any help you can offer.
