Dear Welder Series…
Bought a mustang 2 crossmember kit that takes coil overs last year from your website… Wondering if the mustang 2 stock control arms ( upper and lower) will work….
They will, but it might be hard to find coil-overs that will fit the lower arms, the upper mounts and clear the stamped upper arms.
The lower arms require a coil-over with a fairly high lower spring seat to clear the stamping. The lower coil-over mount will need some spacers to make up the inside dimension of the arm. The hole in the stock lower arm takes a 7/16” bolt, so it would have to be opened up to the size of the coil-over lower hole.
Our coil-over kit upper mounts are for conventional-style coil-overs that have an “eye” top mount. When you order coil-overs for the stock lower arms, the person filling that order will think you need a coil-over with an upper mount like the stock MII shock, which can be thought of as a threaded extension of the shock shaft. The hardware in our kit is 1/2”, so you should be sure the coil-over upper is for a 1/2” bolt.
The stamped stock uppers are bulkier than tubular ones around the ball joint and I’m not certain that they will clear the coil-over spring when the ball joint is in a low position (as when the frame goes up).
Seemed like a simple question but there is a more involved answer. I hope this helps.
Ok thanks for the fast reply. So I guess I should use tubular control arms… Should I use narrowed ones or the regular ones? As for coil overs what do you recommend to use or brand to go for? And lastly for power rack and pinion, can I use a 78 mustang 2 or is there one you recommend to use with your crossmember?
If I would’ve gotten the other crossmember instead of the coilover ones… The stock control arms would’ve worked?
Please email me back on to what control arms, power rack, and coil overs i should use for my truck…
Lastly, I’m driving to Ontario in a few months for a few weeks and visit the folks, I was wondering if I can drop by your shop and drop off a running board bracket to be remanufactured ( I would need 6) and I’m planning to buy a 4 link but don’t exactly know where to start. Would you be able to give me quotes for the bracket?
Thanks a million Paul.
James, the tube arms are more money, but maybe not much more when you add the strut rods, bushing, and gussets. The ride with the tube A-arms will be much smoother. I’ve had both on our ’40 Ford and was amazed at the improvement from a good ride to a great ride. Stock or narrowed arms depend on the brake kit.
I don’t think it matters whose North American made control arms you use. The ’78 power rack you ask about will be fine. If you have to source one, it will be easier to find a ’79 and newer Fox body power rack. Regarding coil-overs, I suggest you check with Canadian street rod shops to see what their policy is regarding spring exchange, if required. It will be easier to change springs when dealing with a Canadian company rather than with US and Canada Customs. I realize these are general answers but there are several good companies making and/or selling those parts.
I hope this helps, too. Thanks for asking me.
Thank you for the info good Sir! I will swing by your shop soon enough and planning to pick your brains more than I already have! Thank you again
I realize I did’t answer about the running board bracket. I’d need the bracket for a few days while I do a CAD drawing. Then I can quote it.
I’m not at the shop all day, every day anymore. If I know when you plan to come, I’ll be sure to be there or see if another time would suit.
