Will a Holley 1920 use the same trans linkage as a 1945? Are there any pieces I need to do the swap or anything? Thanks |

Most likely it will, but I dunno if your car has all the emission packages lines and stuff... you might wanna check that with Dan or other authority in mopar's evolution. Years don't correlate BTWN american and argentinian cars so I can hardly be of any help. (ever)

Slant-6 1bbl throttle linkage is virtually identical from '68 up. Same goes for auto trans kickdown hookups. Choke pushrod hookups tend to dance around a little, but that's easily enough worked around. '74-up carburetors have inbuilt throttle return springs; '73-down carburetors don't. Again, not hard to work around this. '73-up carburetors have provisions for EGR, '72 down carburetors don't. '71-up carburetors have provisions for ducted fuel bowl venting, '70-down carburetors don't (with the exception being '70 California carbs, which do). '70-up carburetors have provisions for thermostatic air cleaner, '69-down carburetors don't. Which carburetor to pick depends on whether you're keeping the EGR system functional or not, which in turn depends on what kind of emission regulations exist in your area. |

Fortunately, there's no emissions tests for pre1983 vehicles in Massachusetts. |

That makes life easier for you. I've got a brand-new (not rebuilt) Holley 1920 non-EGR carb that'll work great for you. |

While they may, have built in "return springs," they are not supposed to replace a proper external throttle return spring set-up. The /only/ safe way is to have a nested spring return set-up that pulls the throttle shut.
