It looks like those are made to be installed on the OEM risers.
Can't tell how much they rise, the numbers in the picture don't expand well, but I believe you will have difficulty with the cables.
Maybe not, worth a try.
I think you're right Bill (the bottom curve appears to sit in them). I can't read/see the other pictures either.
It's been so long I can't remember the OE riser height (3 1/8"?), plus whatever they add. If it's only an inch or so, cables may be OK.
