The dipstick and tube you have will work, but the shorter A body one would look better. https://www.usrpc.com/product/chrysler-318-340-360-oem-style-engine-oil-dipstick-tube-chrome/

Same for the thermostat housing. For this, not chrome as the ones available today all leak.

Without A/C or power steering, you only need single pulleys. But the multiple ones will work.
