OK, Ive searched and I have been unable to find the size or how many washers I will need to clear a 5/8 plenum spacer?

What size will I need? How many? will I need longer strut tower bolts? are they just washers from Home Depot?

I could do this with trial and error but, I'm sure a few of you have been down this road before me so could you help me out?

Thanks

 

Read this thread I created. It has some good info for you. Particularly pay attention to page 2. I'm using a different sized plenum spacer, but it's the same concept. Just an FYI, the Motordyne spacer comes with strut bar spacers. Mine, just didn't happen to get the job done, so I picked up some from Home Depot instead...
