Pro rails in assault chassis?

[BarkChomp907]

Has anyone put pro 155 rails in an assault chassis? IceAge says to move the front suspension mount into the upper hole to prefect track stabbing. I am just curious if this is necessary, I would rather not drill holes in my tunnel...

As you likely know, the pro rail profile is different - flatter. There are some great threads and pictures from 7 or 8 years ago on here that show the difference, Mountainhorse posted them. I would trust IceAge - they test alot of configurations. You could also likely run anti-stab with the tips cut in the lower hole - I'm pretty sure that's been done before, too. IceAge would know this, too. Been awhile...
