If you presently have an 038 mag, You would be far better off having it rebuilt with oem parts than swapping for the present garbage everyone is offering. That 038 mag is pretty bullet proof and one of the best saws ever made by anyone. Now saw have computers, so you can't even work on them. And the prices of the new saws a pretty crazy. Just my two cents. I trade my 038 and have regretted it ever since.
