The new cooler is 20mm where the old coolers are 13/16”.
the lml manifold fits quite well. Just need a touch of clearancing on this heat shield mount (bottom rear)
Also, i don’t know if lbz and up will be an issue but lly/lb7 guys, you will need all new bolts. The 3 short ones are too long by about an 1/8” and the two long are wayyyyy longer than your stock ones. I have double stacked washers on the 3 short bolts for now to just hold it in place. You will also need a third bolt for the elbow.
This thing is massive though. Pics don’t do it justice
Thanks again josh for getting this out quick to me
