because the ED one actually clears the oil drain tube
one truck with a 2ed gen single s-300 with a bulleyes spring gate AND THE OIL LINE THATS COMES WITH IT for a single turbo . also one truck with twins looks very nice works very well both ways
The bullseye spring gate fit my truck just fine you get a new oil line with it some one sold you one without a oil drain line ? clears the oil line , I like the way thay look. Its a nice set up.
I think Jack-diesel maybe a little biased b/c he makes the one for Bullseye.
