I have an 10/07 Heritage Softail Classic and was wondering if there is a 21" wheel that will fit without to much of a problem. I have come across a wheel from a 07 softail, would it fit. 

so if axle size is good then it should fit, will i need different spacers or anything

the wheel I am looking at is 25mm and from what I (my daughter) can see there is a 25 stamped on the inside of the fork leg on mine. On my compliance plate it has an 8 for the year code. Will the wheel from a 07 fxstc fit my Heritage or will it be to much of a hassle trying to get spacers made or any other issues, cheers Seve.
