I believe there is a code section that states you can never use the 90 deg except for derating for voltage drop and temp and stuff.
 
Re: 310.16 correction factors

actually you can use the 90 deg table as long as you use a compatible device.But I have since found that the feed thru lugs are only rated 75 deg so I am back to square one.Cant find a 90 deg lug.
