1978 280z steering shaft u joints

Just like the "non serviceable" joints in the driveshaft, we will be replacing the staked in joints on the steering shaft.  As previous posts have correctly noted, they are 15x39 mm, and staked in.  I have located and ordered some u joints from DRIVESHAFTPARTS.COM at a great price and very reasonable shipping.  They are specifically made for staked in assemblies. Part #UJ1540SD. I ordered 4 of them with shipping for $28.52, just in case I damage one during installation.  They also offer a very nice staking tool kit, but I passed on that.  $375 is really not bad if you are doing these type of joints frequently, but budget says a center punch or chisel will do the trick to keep them seated.  The driveshaft joints I got from ROCKFORD DRIVELINE used internal clips to secure them into the yokes instead of the staking method.  Hope this may be helpful to others restoring the steering shafts on a limited budget.  Thanks, John-Lugoff, SC.
