437 is an E192 value. The only one I've found of that value in through hole is at Mouser, and it is only a 1/4W part.
Looks like two values in parallel. 464//7k5 is good.
Mouser stock a Vishay 464 ohm 3W wirewound part at £1.54 inc VAT, but you have to pay shipping for orders less that (I think) £35. The 7.5k part does not have to be high power. The 3W part is 1% and is 14.2mm long and 4.8mm diameter

You need to check from the design whether 3W is enough power too.
