Y'all,

I plan on installing an EGT gauge and having my exhaust manifold Jet-Hot coated, but want to minimize downtime by acquiring spares to do the mods on and swap those in. I can obtain an intake & exhaust manifold off a junkyard W123 (unsure of the vintage) and want to make sure they'll work on my '84 300td. Are all the manifolds the same, or do they at least have the correct form/fit/function?

Thanks in advance,
Shawn
