K1 spring kit where ?

[300DandTD]

OK I give. I think the K1 kit will solve my transmission problems on an 85 300D with 175 k on the clock, Slipping and bad flaring going into 3 rd but also in 4th if trying to climb a hill. I have read many hours of search results and I think the K1 kit might be the answer. I added trans X today and ran the car around for 40 miles but no change. So much for snake oil !!! And yes the oil level is correct. What a PITA that evolution is. Nasty looking oil and I will change the oil and filter soon. Where have you all found a K1 spring kit for sale ? Fastlane appears to be out (my first choice) My Merc dealer apparently cannot see out out of his belly button due to the location of his head (up azz) so please help me out. I would like to do the oil, filter and K1 in one shot. Thanks !
