Can Someone help Me Identifying These Skis

[Aquaholic]

I have a 2004 RX-1 ER and a 2005 RX-1 ER. Just bought them both and i'm new to sledding. I'm wanting to buy new carbides for both sleds but it appears i have two totally different sets of skis on these sleds. One pair looks to have 4 bolt holes and the other pair appear to have 6. Can anyone help me identify these skis so i can purchase new carbides?

The first ones are Yamaha Skis... look like the First Apex Style Plastic ski... then 2nd one with the Alum Saddle are Older Yamaha Viper Skis if I am not mistaken

The second picture is the stock 04 ski with saddle, the extra bolts hold the saddle to the ski. The only difference in carbides should be the length of the studs, 04 would be a little longer.

that makes total sense. the second pic is the skis on the 04. i didn't realize all 6 of those bolts weren't part of the wear bars. when i look up stock carbides they are all shown a 4 bolt so i just assumed the 04 had aftermarket skis that used 6 bolt wear bars. these are low mile sleds i was having a difficult time convincing myself that someone had replaced the skis on the 04.
