Final drive help

[Kellsled]

Opened up my facelift box to change final drive and pinion to a spoon 5.1 but when I counted teeth on final drive already in it there was 81 teeth and there also 81 teeth on my new one. So counted teeth on pinion shaft and old one has 17 and new one has 16 is this right enough or has my car already got an aftermarket final drive in it?

Is there part numbers on the gears to compare?

Not that I seen but I will check, new one is spoon 5.1 or so is says on box haha I thought the more teeth the higher it was

New one is 5.0625

Old one is 4.764

Cheers buddy was worried something was wrong haha if it's shorter that's the main thing guessing spoon just label them as 5:1 for handiness

FYI it's larger gear divided by smaller gear to work that out
