Don't be. We are fully invested. It was a miss. There a lot of things to try and get right and it's not suprising that that happened. There was concern when we realized it, about welding to a closed space with sound deadener in there. No doubt your comment prompted a lot more discussion about should we and how should we. In the end, nothing caught on fire and it's a mistake we don't have to live with. Those boys working on that cab are good.

This board offers inspiration in many forms. And I appreciate it all.

Here is the low mile 1970 K20 with 307 from BAT. This tube is 1970 only, as 1971-72 tubes have the rubber cap.

If you zoom and enhance the BAT K20, it looks like the 71-72 tube and has the "OIL" labeled rubber cap (to me).

I don't doubt you. Super intrigued actually. Lot of little mysteries (still) to me with these 70s. So much one year only stuff.

Right you are. Might be a late change. My March built Blazer has the steel cap, and the base of the tube is twist on.

After a thorough search, I have found the part number for the 1970 only K series with power brake booster oil filler tube. Per a June 1971 parts catalog, it is GM 3929746, and the part is stamped with this part number.

Also used on big block medium duty trucks 1969-70 with 366 and air brakes.

You have taught me something. Thanks! Bringing receipts! Nothing better than pics and part numbers. Love this group. Something else to chase.

The fun is in the chase. Your right though. This board has so much education in it if you know where to look. I spend more time on here researching most evenings than working on my build.

100%. I kinda thought I knew what I didn't know...cuz I'm actively chasing that! More that I don't know I don't know it turns out. I've already said it a couple of different ways in this thread. However good this truck turns out...it will be because of the help and generosity of information from the folks on this board.
