..........I bought a new Osborne chassis assembly manual, and found it there as well. Page 25,view W; Which also supports the part number and supplied information as well.
Wouldn't be the first time that the Assembly manuals were different from what they did on the line
Not that it makes allot of different what is the change date from that page?
Looking at a mid 68 production year MPC page I don't see 371992-S32 listed for your application. I see 371992-S2 listed as a 68 application - no parts carriedlisted for the 67 application, other than for cars with cruise control. Interesting that there is no difference listed between big, small or 6 cylinder nor transmission type. They are described only as a clip
Going through 10K of Shelby pictures did find two though it will not help with the original finish.
First is a very early car in the #400's and the second is from a car in the #2400's. Attached differently. Might just be one of the many running changes 67 is so "famous" for
Not an easy lace to get a picture of - if the engine is in the car its in the way. If its out they often remove or disconnect the speedo almost completely
The design/shape (at least the first one) looks different from the 69 version but can't be sure without each in hand to compare.
