I have a 1984 nissan pickup 720 2wd standard transmission wich had a blown motor and instead of rebuilding the motor I came across another one for 200$ out of a truck with transmission problems anyways i put the motor in got most connections hooked up only thing is the exhaust doesn't want to go onto the manifold was wondering if the manifolds from standard to automatic differ and also the new motor is out of a 85 nissan not to sure if the years play a part both exhaust and manifold are 3 bolt pattern seem as if the exhaust is a little small or won't twist to line up due to bend in pipe hitting near by objects what would be your guys suggestions

If both engines are the same and they are both 2wd then id say most likely.

Id just lay them side by side and eyeball it.

Reuse the old manifold and just visit an exhaust shop to hook you back up.

Use a rachet strap to pull it where you need it.

If you are referring to the 3 bolt collector flange them maybe just redrill or enlarge the holes throw in some nuts and bolts.

Thats all I got... GOOD LUCK!

That's what I was thinking bore the holes out a Lil more I'll try somthing
