They look similar to one I used on a hydraulic clutch conversion. The lever itself is a standard form & the piece that fits to the fulcrum is changed to suit.
What I found was that the lever, being universal, didn't have the correct angle, so that when it was pulled home it touched down at the end, limiting the throw. If the lever had been machined from 7075 I would have had to leave it, but as it turned out, I could simply increase the bend angle to make it fit.
These are cheap enough that you don't lose much if they aren't spot on. I'd go for it.
