If you have the LS1 brackets also then yes they will work.

I can get you specifics when I get to the shop later if you like.

Oops, just noticed you replied. I'll haul *** to the shop as soon as I pull these burgers off the grill.
Are there any specific specs you need besides bolt offset and pattern?

Nope, basically all I'm concerned with is whether or not the truck coil brackets will mount to LS1 or LS2 valve covers and what the offset would be if they will.
Thanks for the help! Hope those burgers turn out well

Ok, I dont know how much help this is gonna be, but I'll give it a shot.
Use this webpage so we know which coils we're talking about-http://www.abearmotorsports.com/coils.htm
The first two pictured are the early (1) and late (2) truck coils. The second two are LS1 (3) and LS2 (4) coils.
At the shop I have LQ9 valve covers (which came with coil #2, late truck), the above mentioned coils 1-4, LS1 coil brackets, LS2 coil brackets, and the late truck coil brackets.
None of the coils will bolt on to any of the other brackets I have. But the three brackets will all bolt on to the LQ9 valve cover. The early truck coils also use M5 bolts instead of M6 like all the rest.
Bolt offsets (center to center) for the coils are as follows: Early truck 2.5", late truck 2.882", LS1 2.585", LS2 2.828".
Like I said, don't know if this helps.
...And the burgers were sweet. Nothin' like bbq-ing your breakfast

I should add that all of the coils EXCEPT the LS1 coil use the small electrical connector.
The ls1 coils connector is significantly larger.

When I purchased my Bailey LTCC Coil per Cylinder Ignition for my LT1, I had to specify which coils I was going to use, LS1 or LS2, because the connectors were different. I went with brand new LS2 coils.

I was asking because I was selling a set of coils, and the potential buyer was asking the question. I ended up selling them to someone else....never figured out if they would work or not.
