Ordered a new “White front Sprocket” but the number is odd!?!

[Don60]

I’ll start by giving a list of what was ordered:

Part# 705503291 - Pulley-Idler Kit RT (which does not have new two bearing wheel by the way)
Part# 250001017 - Screw Hex-Flange (new pulley bolt)
Part# 705503239 - Wheel Sprocket 28 teeth B-356 Painted

When I received the parts, the number on the pulley box was correct, 705503239, but the number on the actual sprocket was 705503244 with a date stamped under it of 01/21 and on the opposite side “built in the USA”. I called the dealer back, they are looking into the new number??

I have a couple questions for anyone.....

1. Has anyone else who ordered a new sprocket got one with this number? Is it actually a better one? and

2. I thought BRP parts were manufactured in Canada?

Thanks to anyone who has dealt with this issue!
