I did mine 8 years ago so I’m sure prices have gone up. There wasn’t much as far as duel pass out there that I could afford. So I got the biggest universal Summit one that would fit , just under $200 and 2 11” Spal fans, $98 each. My son can weld so we moved the bottom outlet to the passenger side and split the passenger tank with a plate and added a bung for the steam port. I made the shroud and mounting brackets. So basically $400 and some fab work. I live in Arizona and have never had an issue, even 115* with the AC on.
Jegs and Speedway have some duel pass for just under $200 and maybe use a Taurus fan ?
