@alabbasi,

That’s pretty awesome! For such a young man he is vary talented. I watched all of the videos. His final driving video was great. You can see the awesome torque the M119 produces. My only comment on his build was the cutting of the holes in the trans and adapter. He did a lot of jury rigging but it all seemed to work.
Welding up the differential seemed odd to me. I thought the SL had a limited slip. I guess he made it no-slip with the welding.
He could make a few $$$ selling a comprehensive “How To” on his project.
Thanks for posting
