Hi Guys,
Ive recently (May this year) purchased a Limousine business in Australia with 5 Stretched hummers (4 Krystal and 1 Presendential). The Pitman arm has failed and ive ordered 2 replacments but both have been too small to fit onto the spline of the steering box by about 1mm they are the 4 groove spline design.

Ive found an old on the shelf 1 that they had part number 26062651Lc but its was just a spline didnt have the 4 grooves annd it fit stright onto the steering box. I ordered one from ebay (as it was the only place i could find it) with thee same part number but it turned up with 4 grooves and it doesnt fit. I am at a complete loss.

Question is - Is there a different type of pitman arm i should be ordering that is the right size to fit onto the spline or where can i order another 26062651Lc that doest have the 4 grooves in it ?

Thanks Mark
