home made parts

[Hoghead]

I have the Eagle Performance part, and it spigots into the torsion bar tube. The idea is to take the load on the torsion tube, but the fit in my 40 year old corroded tube is not so great, and I question on how well this will work.
Current thought is to attach with grade 12.9 Allen bolts and TIG to the torsion casting.

The thread engagement on the heim end joint is about 25mm. A bit more thread would be nice.

I got straight plates for a 944 and not a Beetle with offset plates as shown in the pic. I think he was confused by my 944 arms so be very careful when ordering. The plates are now in Thailand and the freight to bring in offset plates is more than the part.
All I can do is use a spacer or get new plates made here
