1970 Mercury Cougar columns were a weak design from the factory. We find that all the columns we get have some degree of excessive play, some will not even hold position. We send every 70 tilt column that comes in to be reconditioned using a mid 70's donor column. The design was improved upon greatly as the years went by and spending a little more on an updated one is well worth the investment. This is a 100% complete column with key and all parts needed to convert from a fixed to a tilt column. You can use your existing plastic plastic color keyed collar and ignition switch. For not much money you can have it re-keyed for your existing key. The turn signal switch is included but not guaranteed.
