Poor quality control
I purchased Holley 860001-1 Sniper EFI Throttle Body 92 mm. Billet and purchased this IAC I WAS HOPING IT WOULD HAVE BEEN S PERFECT MATCH ,,,, no the IAC mounting PLATE THAT HAS TWO PRE DRILLEDMOUNT TO The THROTTLE BODY ARE Not in the same position as the pre tap holes in TB .. UP .. I WAS GOING TO DRILL THEM OUT SO THEY WOULD LINE UP . But then if it was defective I would have a hard time returning it back for 70,00 i shouldn’t have to perform any modifications so the old one is in and works Do I reorder and try again on the fence I probably will reorder

Where's the hardware?
Fitment is right, however, there is no hardware with this product?

Used in 92mm Sniper TB as recommended by Holley
Replacement for IAC 543-105 that I purchased with the 92mm 80001-1 TB in May 2019. The original lasted only approx. 300 mi. before failure. The replacement seems to be from a different supplier/manufacturer. I had to rat tail file out the replacements lower mounting hole to get it to mount to the TB. Ran a GM IAC for a while as the newer 80001-1 92mm TB uses but it made very loud hissing noises in this throttle body. The Chrysler style 543-105 is 90% more quiet!!!
