Pro Comp 7in lift. Going with Billy 5100's on the front

Hello all. Ok so I've got a Pro Comp lift with original PC struts. Went to 4WP and the said I needed to get stock top hats to be able to use new billy 5100's on the front. And to be honest I was paying a whole lot less attention than I should have been. Went back the next day to pick up my Fox rear shocks but the sales guy who I spoke with was not there. Anyone run into this before?

 

the pro comp coilovers may use a different design. Billies use the stockers, so certainly possible and not too surprising to me.

I have also heard of folks using KYB top hats on 5100s ,6112. I would not sweat it too much, they are not expensive, probably get the two for around 50 bucks
