So does anyone make the brackets to hold up the coil strip? Or can someone link some pictures.

Yes, exhaust ports are different. You will need a manifold and gasket from 97-98 to bolt up to your 0630 head. I had a shop to tie all the exhaust together. Its just not that easy to find drop-in replacements that bolt up to so many different parts. . . manifold, cat, downpipe, etc (especially if you have the 4 O2 sensor california setup, i did not)

Here are my notes from replacement. 5000 miles later, and so far, so good.
