wat would be better for a 65 coupe 4 leaf rear springs or 5 leaf rear springs? and do they handle differently?

 

it depends on what you re doing if you are just daily driver and nothing really performance then the 4 should be ok but if you hop up the motor and do any type of hipo driving then get the 5 but remember it will make for a more bumpy ride

 

4 leaf will give you a comfier ride and will provide decent performance. If you're planning on any kind of performance build then 5 leaf is pretty much essential, as it stiffens up the rear end. 5's ride rougher than 4's but nothing bad enough to cry about.
