Question about replacement of jack receiver tube and pyramid Options

[Richard Casto]

The PO had removed the old jack receiver tube and pyramid due to rust. I am going to replace these (not interested in leaving them off). The rust included not just the tube and pyramid, but also the exterior layer of the double wall longitudinal behind the pyramid. I have removed all of the rusted metal, but all that is left is the interior layer which is recessed into the longitudinal. I need to fabricate the exterior layer. The exterior layer also needs to be recessed but I don’t know by how much. If I go too deep the tube will be recessed too much. If I don’t go deep enough then it will not be recessed enough. I know I could just be safe and cut the end of the tube off if it sticks out too much, but I would rather just do it right and recess it the correct amount.

Here is the current situation. You can see the interior layer, but I don’t think (not sure) that the exterior is recessed quite as far back as the interior layer is.



I have replacement tubes and pyramids, so I know their dimensions. If someone could measure how far the tube sticks out beyond the flat surface on the top of the pyramid on their car, I can calculate how far to recess my replacement exterior layer. So in the diagram below, I know “A” and “B”. If someone can give me “C”, I can calculate “D”. If you can’t easily measure “C” then a combined “B” + “C” measurement (total height of tube from longitudinal) will work as well.



Thanks for the help!

I'll look at my car when I get home and find out for you. That is, unless someone decides to post the measurement you're looking for beforehand instead of just trying to talk you out of your plans to replace the jack post. (IMG:style_emoticons/default/rolleyes.gif)

Regarding the removal, use of jacks, etc. I figured I would have a few trying to talk me out of it even if I said in my first post I wasn't interested. But I am ok with that.

How about measuring the other side to get a rough idea of what you want ?? Is this possible (IMG:style_emoticons/default/confused24.gif)

Doh! Why didn't I think of that... (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif)

...but I can't as the PO removed both jack points, so I have no reference. (IMG:style_emoticons/default/sad.gif)
