RE: T-40 tow hooks
There has lately been an increased frequency of cracks when towing using the front tow hook.
We ask you to consider the replacement of the front tow hook. Instead of attaching it to the front plate, use the sides as a foundation like on the T-20. In parallel, perform additional testing of the current design.
Send your ideas regarding this issue and the results of any additional testing to us.
