You are right Fernando. It was an oversight from my part. My apologies to lawndoggie.
On my Impulse PRO (now already converted to 705), I use a different way to keep the pin in place to help keep the rear floating mount mounted correct. Please see pic attached. I use part of the Streetspec Shock Support mounting 808137 as I do not use any rear shock tower.
Yes, 808139 is not mentioned and listed on mytsn but Serpent does sell it separately. Don't know why. I have and use this on my 705 with TC body but actually never had the opportunity to test it nor the need to use the alternative shock hole mounting.
