Grinding into first gear when engine is warm

My 1952 F1 pickup shifts nicely into gear when the truck is cold, but after it warms up (maybe ides up) it grinds going into first gear. Any easy fixes?

Welcome to the forum. What transmission? What is your clutch free play?

1st gear isn't synchro'd on any of the stock transmissions.

If it is a stock trans there is probably no syncro as mentioned the reason it works cold it that the heavy cold oil acts as a syncro slowing down the shaft in the trans . Proper clutch adjustment will also help

1st gear syncromesh introduced in 1963 with the Ford type 3.03 3 speed. All previous 3 speeds have a 'crash' (no syncromesh) 1st gear.
