What size belt question!!!!

What size belt for 2.80 pulley 100mm idler and HPBH intake spacer?

Ok what is the stock belt size? Is it 75.1" If so I just got done installing a 2.80 pulley with the 100mm idler and bracket, and HPBH intake spacer. The stock belt is too short. If so and the stock belt length is 75.1" then would I need a 74.5" or 75" inch belt length? Thanks everyone.

Come on guys. Help me out. The belt size is not typical due to the intake spacer.

I went there prior to posting as well as Billetflows site but the intake spacer is throwing everything off. Everything sits higher now about 1/4 inch. I'm going to assume a 74.5" belt.

Ok the stock belt size is 75.1" inches and it doesnt fit so I need a 75.5" incher.

Gatorback doesn't come in a 75.5 from what I'm gatering form parts stores. So it looks like it'll be a 75.8 inch Gates.
