Handlebar risers again

[Vabagger]

Found some forged alluminium 4" handlebar risers in Drag Specialties catalog for around 70 bucks with a thread size of 1/2 X 13. Is there anything that needs to be done to the stock triple tree (07 Nomad) to make these work. Hoping to not have to change cables and hoses. I have not looked at the stock mounting system to see if it is studs or bolts being used. This would be a much cheaper alternative to spending $130 for ones from other vendors.

Thanks in advance to all replies.
