zcar63 Posted July 24, 2016 Share Posted July 24, 2016 (edited) Hi All This is not my idea,i pinched it , there maybe other ways to make it work .This is what I did to make it fit. If you find i have omitted anything or missed a step ..................... First ,BE SAFE, jack your car up and use some sound axle stands before working under your car.Take some measurements of the caster arm length to front lower control arm. Use this measurement to get close to what you had after you installing the new arms .Then get it properly aligned as soon as possible. The thread on the Falcon caster arm is 18mm x 1.5 Tools needed: - Pair of Ford XD,XE and XF Falcon caster arms with nuts and large cupped washers - angle grinder with cut off wheel and flap disc for finishing - drill press or pistol drill - 10.5mm or 13/32" drill bit - Marking pen and scriber - round file( Lots of elbow grease if you use this) - spanners or shifters to fit adjusting nuts - bush kit from Mazda RX7 series 1,2 and 3, Nolathane Part no 48021 Try EZIAUTO parts on line Tool that will make life easier if you have them : -18mm x 1.5 die or die nut - 26.5mm reduced shank drill bit -18mm or 23/32" drill bit (to drill ZCar cupped washers) -Die grinder - vice -clamp -powder coating(optional) Zcar in foreground Falcon at the back Thread on Falcon arm extends down further from the end an are larger diameter Knock out the facon studs place z car arm over falcon arm and mark where the new holes go. lop off the end Spot drill ,and then drill through on the drill press Notch out small area to miss the swaybar drop link Drill or grind or file the mounting hole on chassis brackets to accommodate the larger diameter bush kit The hole required is approx 26.5mm with this new bush kit You can drill out the Zcar cupped washers that go either side of the mounting bushes or maybe use the falcon ones Edited July 30, 2016 by zcar63 Quote Link to comment Share on other sites More sharing options...
dat2kman Posted July 24, 2016 Share Posted July 24, 2016 LC or LJ Torana ones are a bit easier to fit. Lot less work at LCA end But well worth the effort, and a darn sight easier to "suare" up a bent chassis! Quote Link to comment Share on other sites More sharing options...
Agno Posted August 3, 2016 Share Posted August 3, 2016 What do you/would you use the 18x1.5 die nut for? To make extra thread on the falcon tension rod near the step? How much more adjustability do you get from this setup? Quote Link to comment Share on other sites More sharing options...
zcar63 Posted August 6, 2016 Author Share Posted August 6, 2016 Hi Agno The die net is just to chase the falcon thread, they often have flattened/damaged threads in spots.In the second photo you can see the falcon v datsun caster arm ,more adjustment available on the falcon arm.
