The front engine covers need to be swapped to run 5.7 accesories on a 6.1, I believe

Time machines sells a 5.7 accessory kit for a high end look and I think it works on a 6.1. I got the 6.1 accessories from Bouchillon performance, they address the power steering issue (or alleged issue)with a couple fittings. Their price for the front accessories were cheaper than MP's listed prices

The alterK makes the 6.1 swap a breeze..
