Grading Blade Numbers

[bluefine409]

Need help before installing new blades on my GT2544. I ordered the Hi Lift blades (#759-3949) and when I picked them up I noticed the #01008616 stamped on the blade. I asked the dealer about this and he said that is what cub sent him for the #759-3949. I did some research on the web and saw where the #01008616 is a hilift blade that fits a 44" deck on a Zero Turn Cub. Are these the correct blades for my deck also or do I return them to the dealer?
(Placing these side by side with the original blades, I don't see that much difference)

you got the right blades, all cubs blades have a 3/4 center hole. width and weight may vary but has no impact on gen purpose of cutting grass.
