Default Those with Huron turbo kits on a 5.3, Couple Q's

So i have a 2003 5.3 block and had never noticed
the 5.3 s were missing couple bolt holes on the stock
alternator location compared to the ls1 block.
1. how did you mount the idler bracket
2. did you modify the alt. relo bracket
for a truck alternator?
Im keeping the power steering also so i cant mount
it on the driver side head.
Thanks in advance.

Buy the alternator bracket, and line it up to mark where the hole will be. Drill it out and tap it. It's a m10 by 1.5 I believe.

Here is what we did to my bracket when it didn't fit the truck block. There is a bolt on the side of the block that works great with angle iron.

taken from my other thread... i switched over to fbody accessories, in my other thread, it has all the part numbers you need, everything but the alt bolts right up, but you would need the camaro water pump, power steering pump and crank pulley... etc

if you are using an iron truck block, you will need to drill and tap the hole for the front alternator bracket and alternator to bolt onto the block (the aluminum block should have this already)...

I used the following, which came with the right bit and tap (for stock bolts), pilot drill first...



the top hole is the one that was done



and the alt mocked up before cleaning and painting it




the rear bracket hole is already there and works perfect, with the alt

sorry i just noticed in the title it says those with the HURON TURBO KIT... i dont have one of those kits, but if you wanted to put the alt down in the fact ls1 location, thats how i did it...
