I'm building a turbo and I have a T04E backplate (Garrett) and a 60-1 wheel, 59 mm (inducer)/ 76 mm (exducer). I'm looking for a compressor cover. I've checked with turbonetics and they make a TO4E covers but none for a 60-1. Their 60-1 is for a TO4B cover. I've checked with Garrett and they make a S cover but it seems to be for a 56 trim. I guess there are a couple of choices but I'm not sure.

(1) I could get a Turbonetics 60 trim E cover and machine it to fit the wheel.

(2) I could get a B back plate and Turbonetics 60-1 cover.

(3) I could get a Garrett S cover and machine it to fit (maybe)

The 2nd suggestion is the most straight forward but I'm not space constrained so I would like a E or S cover. I'm open to suggestions.
