I know it will bolt up to the back of a 261 with an adapter but I'm concerned about the trans mount. It looks like it will be just aft of the torsion bar crossmember. Also I see a problem with front mounts since I will be losing the ones on the old bell housing. Anyone who has done one or read about it, post. I'd surely not want to miss this. Thanks | | |

I can't tell you about the front mounts. I'd say you need help from a chassis fabricator or good welder. | | |

Also, it seems that you are going to have to lose the original crossmember that the rear engine motor mounts were attached to. All this is in addition to what the other response said about modifying the torsion bar cross member. | | |

Very easy to do with steel plate and angle iron. Buffalo's adapter has the holes pre-drilled and tapped for side mounts. | | |

The center floor board is simply bolted on so that will be easy to take out and modify. | | |

I went ahead and bought that 2004r trans w/a driveshaft. It was too good to pass up! I'm thinking that early 60's trucks w/ a six and powerglide had engine front side mounts. It would require drilling my crossmember but that is where they went and I have the mount holes on the engine as well. But better still would be Cletis' suggestion about the adapter from Buffalo. Where do I find them? I have a spare torsion bar support member that I can modify to accept the transmission mount if that's what it takes. I won't know what I'm up against until I mock it up there and I'll probably be in for some surprises. Keep those ideas coming, PLEASE! | | |
