    I am putting a MustangII front end under my 53 chevy 210, i have made 2 sets of pipe style brackets but im not happy with them, so i found some pics elpolako made that were more stable looking and less troublesome. I am tring to figure out the angle of the upper bag plate and lower, the M2 has so much travel i cant seem to find a happy medium, either my bag rolls onto itself at full drop or twist real bad at full lift. any thoughts on this , i would greatly appreaciate it.

    The pic is the first attemp, with the pipe style mounts i have ditched this idea in favor of the plate style mount, but as you can see in the pic the lower bag is rolling in on itself.

    I think the key is the angle the 2 plates are set? i just cant figure out what it is.

    Thanks
    MrC

    here are the pics in question, looks like in both fully lifted and fully lowered the bag stays parrall to the mounting plates and theres no rolling or binding, i cannot figure out the angle of the upper plate or lower mount. I am really impressed with the design and hope to copy it. Elpokalo great work.

    The pictures you posted both appear to be in the lowred position.

    The photo of your current set-up; It looks like you need to angle your lower mounting point outwards towards the spindle more. Unless you run equal length arms, or a HEIM joint on the lower mount there is going to be some roll over in the bags.

    A lower mounting plate attached to a HEIM joint would help your problem some as it would allow the bag to pivot slightly in relation to the top mount.
     
  5. Hey I have seen pictures of Air ride cars in the 40s and then some in the 50s. Not very common but cooler than hell back in the day. Screw the Nay sayers if they even pop up. I love bagged cars. Best of both worlds.

    Trial and error is probablyyour best plan of attack... Unless you can get ahold of Elpoloco and he has the exact angles he can give ya. He is one smart suspension buildin mofo, thats fo sho. ;D
    Six of one, half dozen of the other as far as which mount type to use in that situation. I like his idea but i've done a hundred (probably a slight exageration ;) ) cars with the "pipe" style mounts and had no issues what so ever. Really depends on the car though... Good luck in your quest for the perfect angle. The key really is to find a comprimise between inflated and deflated but also remember that what matters most is how the bag sits at ride height. Thats where it'll be when yer goin down the road and making the bag work. You don't want any extreme angles goin on in that situation. It'll not only effect the longevity of the bags but will also comprimise ride quality as well.

  9. your first pic i can tell its wrong. that bottom of the bag shouldnt be all contorted like that.

    Probably a stupid question on my part BUT..........

    Could you make some sort of pivoting lower mount? Like a wrist pin on a piston that would allow it to automatically adjust to whatever position it may be in?

    Probably not worth the trouble though. Just something else to break.
     
  12. no, i think that would be a bad idea. it could be in a bad position to lower the car and the wieght could cause it to stay in that spot as the car comes down leaving the bag crooked.

    on my bagged truck the top mount is straight up and the bottom of the bag bolts right to the lower A arm. so when its raised the angle isnt to bad.

    Roll bags all day long,nothing wrong with them and they perform well.
     
  14. im no professional by no means, in fact im getting ready to do my first two bag jobs on mustang II's in the next few days....... But im thinking that your lower mount is the reason for your problem..... See Speedway's new catolog, check out how they are doing the lower bag mounts on the stock lower arm..... they are using a lower mount that wraps the lower arm from the top... hard to explain on a comp but check out their site....... type this into the item number Item #: 91034110

    something like this may help to solve your problem as well as be a little safer

    i have seen the kit and plan on copying the lower mount, seems to me the higher side would be closer to the piviot or further away from the spindle, in mock up i have elevated the spindle side 25 degrees, which made it worse, so either im putting to much angle on it or the high side goes away from the spindle, will change it tonight and see what happens. Thanks for the input, i have done bags many times, just never made my own mounts and never on a M2 front end.

    you mean like this, i tried that idea also, and like you i had concerns about it. even in a double sheer, the whole weight of the car would be on 2 bolts.
    I found i still needed more movement in the lower mount to compensate for almost 14 inches of travel, if i hollowed out the entire arm or had tubular lowers, i beleave it would work very well, almost like a shockwave set up where the bag can piviot top and bottem. Just trial and error, as any thing you have never done before.

    this is what I came up with, I like it and theres no binding, lays frame and bag has minimal roll. In the last pic, you can see I added another tab to make the main bolt in the M2 double sheer.
