Silverado tierod flip

I know, I know.....this topic has been covered multiple times but I cant' find exactly what I'm looking for. What is the taper on my '09 silverado tierods? 1.5"/ft? Does anyone on here make tapered inserts to go in a drilled out spindle? Or would I be cheaper/better off going with heim steering? I like the setup Ekstensive is putting on the nnbs trucks. Thanks

I make tapered inserts that press into a spindle and change the tapered hole into a straight hole, then convert it to a heim joint steering, with whatever amount of drop down the customer needs.

The steering kits i make look like this:
