Exporting CA weapons to the source engine

So I have been researching the forums since it seems to have many information about modding and importing models to the lithtech engine. However I would like to import CA weapons including with the animations to the source engine. My progress has been that I was able to switch LTB to LTA and it is in a readable format but now I am in the position where I do not know where to go now. I tried installing the Maya 5.0 from the links that I found in the forums but it has no crack so rip and I am unsure how do you install the plugins on the files found in the forums. If anyone has ideas where I could import the LTA files to a 3d modeling program that could export to source engine I would appreciate your solution.

Don't convert LTB to LTA, because that doesn't make sense, you can convert LTB to SMD and then export the source engine format using MilkShape 3D
