This is from McFarlane Aviation in response to an email I sent last night.
Good Morning John,
Thank you for the inquiry on the springs. Yes, we now have a spring kit p/n 7140 that contains left and right springs. These are colored Red for L/H spring p/n 6822 and Blue for R/H p/n 7235 as seen below. The engineers have developed the new spring for the right side that helps align properly. I have attached the new instructions for installation of the springs for your reference. Our website does not have the new spring or kit listed yet, but they are available for sale. I am not sure if Vans has those yet or not? Hopefully that is helpful information. Please let me know if you have any questions.

They also sent an instruction on how to install, but I do not know how to post the pdf on VAF.
The installation instructions require ?Remove upper B throttle arm piece from the
carburetor shaft.?
