Does anybody know of a listing of kingpins by diameter? I am looking for a set for a 30 Plymouth- they're .750 x 6.25 - and I can't find a listing by make, but I'll bet something else uses that same diameter.
that list does not included `49-54 chevy car , but Speedway says they are .867 if i was was you i'd be tempted to make some new kingpins out of 3/4" tool steel drill rod , and then find some oilite bushings that would work.
here's a few... http://www.droppedaxles.com/Kingpin_Part_Numbers.html Maybe try here... VINTAGE MOPAR DIRECT
I make off-road king pins from 4130 chrome-moly bar stock. They're ground to final OD then case hardened by a local heat treater. You might not need to get that elaborate, but it's a close match to the OEM materials and processes.
Thanks all, I've considered using some 3/4" precision shafting from Linear Industries, then finding some usable bushings, but then I still need the thrust bearings and the lock pins that I had to drill out - looks like on Squirrel's list that Moog 8470 +010 might work with a little mod. On these early Plymouths, the pin locks into the spindle and the whole pin rotates in the (2) bushings in the axle.
The 8470 is for an Econoline. The standard size kit is being produced and is readily available, but the oversize seems to be pretty darn scarce.
You can try contacting Mid-Canada Suspension 204-475-3399. This guys stocks tons of old parts like you need. He has a mind like a computer too, he can likely tell you the part # you need just by memory. He's local to me, so I've gone to him a couple of times trying to find old rare parts that I need, and he's never failed me, but he gets requests from all over North America, so he'd have no problem shipping to you.
I checked my Moog catalog and agree, the 8470B is the only option out of the Moog line. It is a little small on the OD though. It also has funny ends that might be included bin the overall length, which would be a problem for you. Here's a link to a picture of the set . http://www.oreillyauto.com/site/c/d...ck=Search_02856_1335899_-1&pt=02856&ppt=C0106 If you used the 3/4 ground shaft, it will probably be a few thousandths larger than your stock king pin. This might work to your advantage if the bushing material is thick enough, you can just ream the old bushings to fit the new pin that you make.
OK, Rare Parts can make you a set for $203.06. They only list a 31 Plymouth but the dimensions look right 6.255 length by .746 OD. Here's their picture. Their phone number is 1-800-621-2005. Their part number is 30106. Here's a link to Rare Parts photo of their set. http://shop.rareparts.com/smtp/shopdisplayproducts.asp?tksearch=Yes
Link didn't work. Try this: http://shop.rareparts.com/smtp/shopdisplayproducts.asp?tksearch=Yes You'll have to search under Rare Parts prefix and then the part number 30106
It might be more productive to think about fitting the spindles and axle to a large diameter but far more common king pin set. If you had the spindles bored to fit lets say the later Dodge 1/2 ton king pin set and the axle bored to fit the bushings you should be good to go and the next time around who ever redid the king pins would only have to grind the notches in the pins for the bolts and fit the bushings. No hunting around or having to have special pieces made at another added cost.
