I'm in the process of installing new Moog C 655 Coil Springs in my '63 Avanti. Previous advice from SDC members has been to use an insulator at the top of the spring and some have said both top and bottom.
In looking at the S.I. catalog ( page 277 of the new catalog ) there are two parts that look very similar and by their description, sound very similar.
526249 Front Coil Spring End Pad 1950-'66 car all models (takes 4 )
526830 Front Coil Lining Spacer 1/8" thick
Which is the difference between the two? How thick is 526249?
Which should I use?
Thanks
John
