do they have a separate solenoid? i'm wanting to put one on my 6.2, but the parts guys can't seem to look it up by the title (28mt). the guy told me that the one he had in stock for the application that I guessed for him (95 6.5td manual tranny chev truck) was not gear reduction b/c it was like the older style starter which has the solenoid attatched to the starter, versus being all one unit. any thoughts???
