Hi J. Glad you started all these boot questions, it makes me read and learn , LOL ! On the 1961, it a K10 Panel truck with 30,000 OG miles and the boot was on it when I got the truck. I will be posting pics very shortly. Jon

Also, back when I first got it, I don't think it had seen much use for quite some time. Then after driving it around awhile I noticed strange black rubbery goo slowly dripping off the top of the trans onto the driveway. This I am now convinced was the foam seal that had degraded with time and was melting with the heat of the trans. At the time I thought it might be the remains of the missing boot that was melting, but now the foam seal makes more sense.
Oh btw Jon (60-66), I am continually impressed with the completeness of your truck and parts obsession. You provide a very valuable service to the serious truck enthusiast. Thanks for that.

That's funny you say that about the "dripping goo" . I have an NOS one I found upstairs in the attic that melted IN THE WRAPPER ! Just trying to help and learn myself as we go along,Im glad these subjects come up. I have an original 1960 K10 short bed fleetside custom project Im collecting parts for so this helps. Jon

Heres a few pictures of the 1961 K10 Panel. Boot looks like its been on there awhile but I have my doubts that this is correct. If you look close you can see the seal coming through the floor that I posted earlier.

This is the floor in my 1963 GMC 4x4

Heres the floor in my 65 K10 32,000 OG miles. Shows trans seal from underneath. No boot on trans and the transfercase boot and retaining ring are under the matt where the 1960-1963 is on top of the matt.

Have a pretty much unmolested 64 GMC with factory sm420, no boot just foam seal that is placed over trans top cover before it is installed. Most have degraded and turned to ooze. There are no drilled or punched holes on the trans hump either , further evidence of no boot ever being installed.
