Try local friendly auto parts store, asking for a similar year after researching parts manuals with friendly (again) employee that U have cultivated a relationship with. e.g. Same year Chevelles are bout same as Plymouth with coil suspension, bring in your Ply shock to check jounce and rebound lengths, and buy em!!!!!!! In fact jounce and rebound (more or less) standard except for HD suspensions? methinks about 64 thru 69 CHevelles do the job. Minor filing of the lower mounting bracket if I remember right, and use 3/4" washer on bottom. Worked super on my wagon. Larz |
