Hello folks, I am going to do what Lou and Doctor Dodge and others suggest in another thread (MANY thanks for the opinions, guys).... make a crossmember to support the rear of my A833 OD going into my '64 d100 truck. Unlike you valiant and dart guys with little room to work, I have what would would look to you like warehouses of space to play in. So I have options...but the basic question is, is it ok to use a flat crossmember and bolt the tranny directly to the crossmember only using a flat rubber spacer for vibration elimination between the tranny and crossmember? This would be easily done by removing the existing little support on the tranny that has the round rubber isolator through which a bolt holds the tranny to something in a car,. If I remove it I will have the nice flat mount seat on the tranny to connect to a flat crossmember as above. Reason I ask is, this is easy, but I can also create a crossmember that incorporates provision for using the existing little mount if that is better. rock '64d100 |

Use the little rubber mount,,,you will be glad you did. Otherwise the vibration and noise will make you crazy. I usually use the factory insulators or mounts as they are best designed for the job. |

I am using a Chevy biscuit tranny mount on both my trans swaps (A500 and T5). Cheap, easy to find in rubber or poly, two bolts to trans and two bolts to X-member. Might be easiest for a stock Mopar trans to use a Mopar biscuit. Lou |

The trans mount needs to flex to prevent damage to the drivetrain. Unless you're using solid engine mounts also (and even then if you figure how much the frame itself can twist), the engine torque will put a pretty good torsional load on the transmission, which will crack something, probably either the bellhousing or the tailstock. |

Try this idea on for size; it comes from being able to swap rear ends from the 63-71 body style to 72-80, and from 72-80 to 81-93 and back; the frame widths are the same as the rear leaf spring perches match perfectly across these different series'.. (I've done it several times) I wonder if you could use a trans X-member from a newer series truck maybe just having to drill a few bolt holes?? Would make it easy, huh?? I see tons of the 72-93s in the yards around here. Just stay away from the 89-up models with the OD auto trans. They are a way different setup. |
