Maybe there just needs to be some proof of it in a moving car to get the orders in.As far as I know, they should work behind any CIH that is mounted straight up (Manta, Ascona, Kadett, 6cyl?), not tilted like the GT.
It would be great if more people got in on this to bring the cost down....for my own (and oem's) personal interests!
unfortunately once I have my car moving again I won’t likely be making any more plates. 😂
