Probably wheel balance.
Tire out of balance, bent wheel, defective tire, worn suspension or steering parts. Have the tires balanced, and all parts inspected.

COULD BE FRONT TIE ROD END
Tire out of balance, bent wheel, defect in tire, or suspension parts worn.
One reason a cars front end may shake is bad struts. However, it can also be other things such as a bad tire or even if an alignment is needed.
I would suspect a bent wheel, but it can also be a tire out of balance, loose lug nuts, bad wheel bearing, or worn steering or suspension parts.
coz your car is a wenner
if this happens at a certain speed it's probably the alignment of the tires.
check the front u joint they May be in need of replacing....grab the front drive shaft next to the yoke and universal and try to see if it has play if so you need to replace You should have the wheels and tires balanced, check if wheel is not out of round.
Thankfully mine does not shake, thanks for asking. This is really not enough information to diagnose the problem. Does it shake the same every time or does it not shake or shake less sometimes? Is the "check engine" light on? Is there a speed where the shake is more pronounced? Does it have to be full throttle acceleration or does it shake under light acceleration too? Is there a noise accompanying the shake? If you accelerate around a corner is the shake any different? Left or right turn make a difference?
The maximum speed of the 1963 Isuzu 350 pick-up 4cyl 72hp is 96 mph.
