62 steering shaft coupler

I have looked but not found anything on the early steering shaft couplers. The only ones I found anything on were the ones with what looks like cast housings that are secured with roll pins, mine looks like a stamped housing and uses a clamp and bolt to secure it to the steering box. The cover came off the housing and I cant get it to stay on. I have seen a clamp made of wire rod for the "cast housing" couplers, is there anything like that for the "stamped housing" ones? I have the fsm for my 62 Valiant and do not see anything as far as repair on the coupler in it. I tried for about 2 hours to get it to stay but it keeps popping off when I shift into low/ reverse ( 3 on tree) does not take that much to pull it into l/r fork on collum, coupler just pops apart easy!

Thanks for any help you can give me.
