In a previous post, Sully Sullivan provided this supplier info for the radiator bushing:
"When we received our new radiator it was apparent that we needed two more bushings as the old radiator only needed two. I also wanted new bushings.
Through Burk Morgan I found out that the bushings were supplied by Trelleborg Automotive
South Haven, MI 49090, but they will not sell to us or Cummins. This caused another week delay as we had to go through their distributor
Mission Sales & Supply in Mansfield Texas,
The bushing is`part #20-02796-01
FS Mount 45
Drawing # 55/1196"
