    '79 CJ-7 4BT, NV4500, D300 w/ 4:1, D44 Front w/ ARB, AMC 20 Rear w/ Powertrax. not so much original anymore, though it may look close.

    the ad says 2nd gen, but it does mention 3rd gen just having 4 holes.

    Those look great, but is there any safety feature for if the rubber tears?

    Part number on them??

    I never thought of any safety feature.? I removed my AMC 360 in lou of a 4BT and just decided to mimick the original motor mounts in my CJ-7. I have no reason to believe that the mounts should tear, but I'm open to any input here.

    Part number ... I don't know. But you can find them in any Jeep catalog or any good 4x4 shop.

    Default Motor Mounts for a Ford

    Has anyone tried using the 6bt mounts from Autoworl in Montana or from Fordcummins?

    You guys that have repowered Fords, did you fab your own mounts or go another directions? I've been thinking about trying to fab a set for my '95 F-150, but I'd feel better going with some off the shelf ones if possible.

    Default Crossmember/Diff clearance

    Off-topic but if that pic is representative of your mounting location, will there be issues with crossmember clearance and front Diff during uptravel?
    Is that a jeep CJ/YJ chassis and front dana 30?

    I assume the 3.5" is the same clearance as between the springs and their max travel bump stops for compression? Also may I humbly suggest that you consider some flat 3/16" to 1/4" plate gussets at your weld zones, in front and behind? Just enough to reinforce during the infamous 'Cummins shake' at shutdown. With almost a dozen beads there is a chance for stress risers or hydrogen embrittlement and future fractures.

    when we cut out the angles we reused to scraps to do that on the inside thats why theres two beads on each angle. and for the springs its about right the springs dont have much flex in them

    Is the 3.5" clearance measured "now" at an unloaded ride height...you may want to factor the significant weight and loaded spring "sag" that will occur once the 4BT is mounted inside the rails. A somewhat economical option /solution may be a spring over axle (SOA) lift but it is still $ and there is a host of steering geometry and axle-wrap considertions...gotta love projects - overtime/overbudget!

    ya we are bolting in the cross member with grade 8 bolts so there is some room for adjustments once we get the motor installed. also we have a 4" suspension lift so it already has upgraded springs and they are STIFF.

    My mounts. used the P30 engine brackets, frame brackets and the original 5.0 driver side mount. The front corners of the block are a little close to the cross member, I will either notch the cross member or fab spacers to lift the mounts up but I'll wait until I get the 9" rear installed.

    Very tidy!!!

    A bit tight like you said. That crossmember is awesome, I wouldn't
    try to notch if all I had to do is successfully shim up the motor 1/2"
    at the mounts. The crossmember is in a very good place structurally,
    and tying into your frame that close to it is great. You will have less
    frame roll and the load will distribute really well.

    So the question is "Will you get interference at the tranny hump or
    the hood or elsewhere if you go up a bit?"

    (That is one of the more straightforward 4bt repowers I've seen on here)

    Thumbs up

    That's very ingenious use of existing hardpoints DarylB

    Is there gussetting under the (Blue) mount plate? Pretty important
    to strengthen the fore/aft direction in case of repeated hard braking
    or a (let's hope never) front end collision. (I realize those plates are
    super thick, well over spec, but the hard corners are places of stress
    concentration.

    Thanks. I've got about 1.5" between the top of the turbo and the hood so I've got plenty of room to go up, that's most likely what I'll do. The tunnel isn't a problem. I also used the original tranny cross member in the stock location so I can use the original rear drive shaft, not sure about the front yet with a 3-4'' lift for 36's.

    They're welded all the way around w/ 7018 low hydrogen. If anything is prone to break it'll be the weak CJ frame before the mouting point breaks. If you notice on the driver's side I had a crack where the factory seam had broken and a few cracks. We welded it all the way up, and down into one of the bolt holes where it had cracked. I'm going to clean up the mounts later & Grind them down. Also my logic was to span the weight of the engine, between the two points, as to not already stress a weak frame. Thinking about doing a CAD design on them and see if They'd sell

    Figured I might as well throw my mounts in here. Used Dodge Cummins rubber, the stock plates on the frame (cut down a bit) and fabbed the engine side.

    Thanks! I ended up cutting up the $100+ AC mount I got from cummins because I liked those mounts so much Ended up being easier to cut up the AC mount and brace it rather than redoing the passenger side mount.

    Now if I could figure out how to get paid more maybe I could finish this damn thing this year

    Default 1973 Bronco Motor Mounts

    I modified the factory motor mounts from I ground off the Bronco frame. The picture show a few of the steps. It looks strong, factory, and maintains the original transmission and transfer case locations.
