| Post subject: | Hydro subframe tower bolts |
Hi all (1) I have 2x hydro subframes The stepped tower bolts are 5/16" unf at 1 end & 3/8 unf the other. The 2 subframes are different. 1 has 5/16 the other has 3/8 in the head of the tower. Which one is right, or it doesnt matter. (2) Should I fit the studs to the towers & then fit the subframe to the car or fit the subframe then the studs? (3) should I use the stepped studs or buy some bolts? Thanks Craig |

I think the original size was 5/16. I'd say someone has stripped and retapped the holes. |

All the hydros I have seen have beed 5/16 with a bolt. Rubber subframes have been 3/8 with the stepped stud. |

I have just stripped two front hydro subframes, one from 1972 the other from 1973, and one has the 3/8" and the other 5/16". One had studs, the other bolts so obviously at one stage they were manufactured so and NO they haven't been drilled and tapped. |

So, do you reckon it be better to use 3/8 bots or the stepped studs? Craig |

I would choose the best looking subframe. Check the displacer mounting lugs up inside the tower. If they are the same, I would use the studs as they may give more support. |
