You MUST machine the mag well AND weld a front latching spot for the mag, do some work to the trigger assembly and change the mag release. All just so you can use an 8.00 mag? Once done, it can not be undone. If you must have an SKS that takes those mags, then just get the D, M or Sporter or an AK as mentioned above. The work is already done for you professionally and will be cheaper in the long run. Yes, I fully understand the wanting to do it yourself. It's kinda like doing 3,000 worth of body work on a Mustang to make it look like a Camaro, so you use the Camaro rims. Just go get the Camaro with the rims already installed.
