I used the purple spring already(firmest option for K-2) I have another 300d with the 2-3 flare. I tried using the red spring for normal shift and though it made it better the purple spring would be ideal. Any one have one they didn't use?

just ran out to the garage and i do have a purple spring left over ,but for my 83 300td it was for the k-1 valve. would it work for you?pm me if you want the spring .
