where to buy spring perches

I'm looking for a spring perch set for a model A axle and wishbone. Like these in the picture except in plain unfinished metal with a castle nut.
Anybody know where to purchase?

 

I buy them from Speedway Motors

 

I was looking at all the usual places, Speedway, Summit, Socal, Pete and Jakes. All of their perches are listed as having longer threads to allow for use of their shock mount. I was hoping to buy one the right size and for use with castle nut. Seems like an item someone would sell.
I guess I'll just cut them down, drill my own hole and buy a separate nut.

 

If you are looking for original style.I got mine from MAC's. castle nut and all.

 

Yep, get them from a resto place like Macs or Snyders. You'll pay more but that's what it costs to look original!

Of course, I buy original forged ones for $5 or $10 a pop at local swap meets. They may need new bushings but mine all say 'Ford' on them!

 

Ditto el Scotto!

 

Sacramento Vintage also has Model A pieces available or in stock.
