    Hello there. I just purchased a 1957 Ford Country Sedan (wagon). It has a sbc 350, TH400, early Monte Carlo front clip and a factory 9" rear. Two different wheel patterns. Is there any options other than unilug wheels or swapping ford rear out to Gm? Thx

  2. It it works well now, do the dual pattern wheels
    Or keep a wheel adapter for the spare.

    ^^^^this. You can change the axles or the rotors. I hate it when there is 2 different bolt patterns on my cars. I have Fords, Olds, VW Dune Buggy...everything I own is 5 X 4 3/4. One set of paint rollers that fit everything I work on.

    "Early Monte Carlo" could mean 70/72 that takes a different rotor than 73/77. 70/72 having the caliper brackets that bolt to the spindle while the caliper brackets are cast onto 73 and later spindles. A dual pattern wheel is the cheap way to go until you figure out what you want to do. Even after that it can still be the spare. Early Monte carlo rotors have a short hub sticking out while the later ones stick out noticeably more. Screenshot (357).png Screenshot (355).png

  10. I had a rod with Chev 4 3/4" bolt pattern on the front.
    When I installed an 8" Ford differential, I took the axles to a nearby machine shop and had the redrilled to the Chev pattern and lug bolt diameter size.
    I redrilled the brake drums myself.

    Then I added 100k miles on that rod.

    Really depends on the wheels and the funds available.
    I'd prefer to switch to all Ford on a Ford, but if OP already has a bunch of GM wheels, redrilling the back may be the way to go.

    Good catch, @Mr48chev, that's why I included the listing, so the actual part and application was clear. Nice showing and telling the differences!

    If your wheels and tires are the same at all corners then yeah fix it to where everything is the same so you can rotate the tires. But if you have big and littles then I’d get a unilug spare

    Well at least you know before you had a flat. Unlike me who change the entire driveline from a crash 64 Falcon Sprint conv. into a standard 64 Falcon hardtop. This was a 260, auto, with the 5 lug rear end that came with the Sprint. As you all Ford guys know, the standard number of lugs for a front for a 64 Ford Falcon is four (at least on the one I had. I found out one late night in the middle of no where.

    Depending on what kind of wheels you want to run, I prefer a 10 hole, dual pattern steel wheel over a Unilug with the oval holes and washers and whatnot. Especially if you're running hubcaps/wheelcovers, the 10 hole dual pattern wheels are the way to go.

    Hello,

    Your car is set up differently, but consistency is what makes things fit nicely and work well. First of all, the easiest thing is to let a good machine shop redrill all hubs to have the same pattern. That way you will not be obligated to always have something different in front versus the back. The unilug wheel was a fancy way to adjust those patterns for the style of wheels presented. They were ok, but there was a right way and this unilug way. No adapters or anything else should be between your choice of wheels, wheel lug pattern and driving. That module helped some folks, but it was only a band-aid.

    The pattern from all top manufacturers of wheels were drilled or cast for an exact fit on each car model. Think about it… most of us carry one spare, full size or small. Some new cars don’t carry spares at all, but have puncture proof tires and an auxillary air compressors for emergencies. So, there is that. But, back to the spare tire dilemma, are you going to carry one or two spares for the front/rear wheel problems?

    Spend the money, find a good machinist to redrill and replace the hubs to match one or the other of your choices of bolt patterns. Stay away from the unilug adapters. They are just that. Folks here have said that constant replacement of the wheels need to take out and put back in each unilug, as the tire changes come to play or a work solution is needed. A simple flat tire may cause you to have two spares. What if you loose one of the unilugs or it is not a solution that I would like.

    Redrill all to one brand or size to make things simple, yet modified to your specs.

    As a teenager, going on 20s, I had enough money to have a top notch machine shop redrill all of my Chevy lugs changed over to a Buick bolt pattern. I was heading for a new look for the 8 year old Impala. I had just purchased a set of Buick Skylark wire wheels and needed a Buick bolt pattern. Adapters were not safe and would not work, so, the shop redrilled all holes and they fit like it was made for the Impala.

    They looked outstanding and for a year or so, they lasted on my 58 Impala. But, one dark summer night, someone stole the Impala and we found it 4 hours later in a dark corner of a park near the traffic circle. Gone were the Buick Skylark wire wheels. So, I had to get new Buick steel wheels and paint them black for the last several months before I went away to college.

    At least there was one spare and it was a Buick Bolt pattern. YRMV
