The spur gear is 87t (48dp) if I'm not wrong. But what about the int gear ratio for both mid and rear config.

Durango told me the ratio is 2.6:1. 3/4 gear config. was not specified so on that basis one would presume it is the same for both? Happy to be corrected though.

RW racing also do spurs in other sizes

It can only be the same, number/size of idlers does not affect the ratio.

unless the idler gears are different sizes

still doesn't make any difference even if they are different sizes.
at the end of the day (god I hate that saying) it's the layshaft cog size against the diff cog size. what's in the middle doesn't matter.

I think you find it does, only if there's a belt between them it doesn't. :p

why would a belt make any differnce the calculation is layshaft divided by diff=internal ratio.

Idlers make no difference to ratio, no matter of size. Only gears driven by or driving a shaft affect the ratio.
