1971 EXT.  I bought this sled about two years ago as a rolling chassis with a bunch of wrong parts on it. With lots of help from a couple friends (Randy Moore and Andy Elliot) we got it together and running great. I put licence and insurance on this sled and have taken it on the trails, much to the surprise of the local trail wardens. They don't have the same love for the blap..blap..sounds of  stinger pipes.

1970 - 640 TNT. I bought this sled from a farmer in the Orillia Ontario area.  The chassis was pretty complete but it had a 440 JLO motor in it.  I needed a big powerful snowmobile as
a rescue sled to tow dead sleds home, my two boys have elans and are better "taker aparters" than "putter togethers" I was just going to get it running and leave it, but kinda kept going with the resto. This sled has a few neat parts like, A 1969 - 669 TNT motor, rebuild from top to bottom, a 669 TNT hooker header, might as well make some noise, 1970 ski-doo blizzard handlebars, new 70 TNT heat seemed seat cover, a NOS power block clutch, engagment about 4500 RPM. There's no fear of sneeking up on anyone with this thing. 

Thanks Dave, it's great that folks like yourself take the time to support and promote our hobby. If it wasn't for people like yourself, there wouldn't be the interest in vintage sleds.  Thanks again for getting the word (and pictures) out.

No Doug, Thank you for writing with the details about
these 2 classics!  Congrats on a great job of restoring these 2 sleds!  The history behind how people came to own these classics make great reading!
