Early A Lower Steering Column Seal

or you could do as one of the users on here did and put in a bearing
1" Insert Bearing, ER16, ER-16, SER205-16, NEW


found on ebay as part listing

that way you get support, hot air blockage AND it doesnt wear out!
for between $6 to $10 plus shipping
I did my spare one but I had to take the shaft out of the column and add the bearing,slide it back in the column and then position it. does it look stock? nope but it works!
