Need to find the bushing for slim Jim trans it goes to the bell crank assy 4.040 and 4.035. The bushing goes in large hole on bell crank and is 1 2 inch hole Rod 4.035 goes in bushing which is 14 inch hole if anyone knows of one or some replacement please let me know oldpac62

 

The numbers you are quoting are group numbers . Group numbers only provide a brief description . For example , all exhaust valves , no matter what they fit , are group 0.297 . All water pumps are 1.069 , etc .
You get a group number from the illustration , and then go to the parts list for the specific number .
Looks like you need one of # 579785 and two of # 581969

 

Charlie I just went by the pics you sent me before. Sorry don't have parts book I will try to find parts thanks. Oldpac62

 

I have an entire 1949 thru 1963 Oldsmobile Master parts catalog that I have scanned into my computer . Over 2000 images .
I'm working on a deal where I can get them on a "cloud" . So that they can be downloaded by anyone . Stay tuned .
