need part number

[moto mundo]

I need starter clutch number for a 2008 electra glide ultra classic.
I got one but it was 3/8 longer then the old one, I did not want to install it
because I may damage other parts.this is the part number 31633-07
can this one work? help.

The part #31633-07 shows for both '07 & '08 models per Ronnie's microfiche online.Was that the part # for the one that was 3/8 longer? Part # 31633-07 shows several different parts with it as a kit.The part #31681-07 is for just the starter clutch itself.
