don?t know, could be. They have no photos. I would be surprised if there is
more than one group making these.

Scott,
Do you know if the Jigsaw vertical links are the same as the undrilled
vertical links offered by Rimmers?
Jason
I?ve been using the trunnionless front suspension vertical link on my GT6 that
Canley Classics sells for the past two years. I?ve now had two fail the annual
magnaflux tests. They cracked in different locations, one right at the
machining line for the flat for the stub axle nut, on the back side where the
steering arm passes through, and one on the upright at what appeared to be a
casting mark, near the bump you see in the photo below. Neither crack was
visible to the eye. The upright Canley sells no longer looks exactly like the
photo - it now has a machined area on the back side, away from the wheel, much
like stock ones. Maybe I just had bad luck, but between two cracks and some
binding issues at the ball joint I had to rectify, I would no longer recommend
these.
I started using the Canley units when the stock ones developed cracks in the
traditional place at the top end of the threads where the trunnion is.
I have now installed uprights I got from Jigsaw Racing
https://jigsawracingservices.com <https://jigsawracingservices.com/> - Mark
Field, in England. The main difference from stock is they are not drilled for
a grease fitting or grease boring down into the trunnion, which should make
them stronger where the stock ones usually fail. Mark races Spitfires and GT6s
for himself and for customers in vintage racing and claims he has never had a
failure. He further claims that the units are made in the original forging
molds and by the same people that made the Stanpart units.
Main point is, even though it?s a pain, pull your critical parts off and get
them magnafluxed at least once in a while. I?ve become paranoid and this is
now an annual exercise. The machine shop I go to usually does it for free
while I am watching, probably because I?m usually dropping off engine parts
where the real dollars get spent!
