You may be able to use your orginal throttle linkage, try it first. There both from trucks.
A 1953 1/2 Ton truck probably has an 11" clutch, so It's okay if in good condition. Check the 'pilot & realease" bearings though.
I'm not 110% sure on the 53 head switch. Use the 58 if you have one that's good. The heads probably interchange, but there may be a difference in the rocker oiling. Best to keep those (engine parts) from the same era.
You'll have a complete 53 to sell someone that want's to lose a 216, as well.
Happy trails.
