Brake Lever difference between standard Hyper and SP

Hey guys I have a quick question for you SP owners out there. I recently bought some cheap levers from ebay to adjust the brake lever closer to the bar. When I went to install the brake side lever it did not fit, as the stock lever utilizes a little plunger to push the master cylinder. The new lever has no plunger and no place to re-use the plunger from the stock lever. I contacted the seller and he said the levers I bought were for the SP. The ebay set I bought has a large machined block that looks like it would just press up against something, idk if that style is similar/same for the SP or if its just is different from the hypermotard altogether. I can put some pictures up later today to help. But let me know your thoughts as i need to know if I can get these levers returned or not. Thanks!

So that means they are different? I believe I simply ordered the wrong part. i.e. SP lever will not fit standard hypermotard and vice versa?

Thanks kuksul, that graphic is very informative. I think you answered my question!
