Fellas I picked up a set of truck/ls3 style coils from a crate engine. What mounting bracket would I need to get the to fit properly?

 

Are these the ones with the heat sinks on them?

 

No, they look identical to the ones on my ls3.

 

The coil brackets for a 2008 LS3 Corvette is 12580353.

What vehicle are you installing these coils on? If it's your 1999 Trans Am, installing the LS3 coils (and brackets and the needed different coil harnesses) won't give your car any improvement over the stock LS1/6 coils.

 

This is the part number to the coil. I'm currently overseas and had my brother check. 12611424

 

Correct, they are going on my Trans Am. My rde is approaching 160k miles, I got a good deal on them about a year ago and figured it wouldn't hurt to replace with the next tune up. If not, I will just save the as a back up for my Vette.
