[DeTomaso] Help needed with lower a-arm shaft kit installation

[Tomas Gunnarsson]

I bought my stuff from Kjell Jansson and it was supposedly factory parts. I do not recall having to use force to get the shaft in place. I do however think that Kjell has found a second source for the bearing inserts which indicates that they are an industry standard product.
