i presume u r goin to run it in a rwd
cause the manifold would face wrong way in a fwd
i recently wired up a 4ag fwd with modified manifold to fit in a sprinter
was abit of muckij round gettin corr3ect alternator brackets and make water pipes to fit the rwd
u also need the correct water pump and outlet otherwise the outlet hits alternator
i cant remember whats diff on the water pump but i had to change it too
