Hi Steer Knuckle Question

Hi all, so I'm hoping maybe you knowledgeable folks here can help me identify what flat top knuckles I have based on the part number of "620243" cast into each of them. I was told the housing they're on is a d44 from a dodge. I don't think I'm gonna run them for two reasons.

One: I doubt they'll work with my chevy small bearing spindles and caliper brackets

Two: they look kinda thin and weak in certain areas. Any help identifying these would be greatly appreciated. If needed I can get a photo up.

They have a typical 6 bolt chevy disk brake spindle pattern. I'd run them if you guys thought they'd be good enough, if my small bearing spindles and brakes will fit them. They just look kinda thin in areas.

I also have a mid 70's drivers side flattop chevy knuckle and it's got way more beef, but I only have the one. I need a passenger side to match it.

Tipped, I would use the Dana 44 flat top knuckles. There is a lot more material where the high steer arm would mount. Check out www.nw-wheelers.com

They are a local board and I know someone on there has a set they will let go for a good price.

Beat it to fit, paint it to match!

Might find some relevant info here: http://77cj.littlekeylime.com/flatop_knucles.html

Your spindles would work on them, but the Dodge knuckles have the caliper mounts as part of the casting and Chevy calipers aren't compatible with the mounts.

Chevy knuckles aren't hard to find. The plus side is the drivers knuckle you have should be milled/drilled/tapped already for a high steer arm.

Well I'm still hoping someone will chime in and help me figure out my knuckle dilemma. I've searched high and low, came up with nothing for that part #.

You might try posting a picture. I have no idea what casting numbers are for the knuckles I can recognize visually.

I'll do it. I just need a little more time. I'm welding the inner knuckle I pounded on last night.

Here's photo's of the knuckles. They don't look nearly as strong as the one driver side flat top chevy knuckle I have. I need a passenger side chevy flat top. Just got back from the picknpull. Not a single one to be had

I'm one step closer to knowing what they are. The CJ5 Dana 30 knuckles looks identical. The difference is the CJ5 D30 knuckles have their caliper mounts cast into the knuckle itself. Well my question is answered well enough based on this new information. It's basically a Dana 30 knuckle. End of story.

Got tired of goofing off. Found a beef Chevy pass-side flat top sandblasted, painted, milled, drilled and tapped for 150 + shipping of $14 outta Oregon City, Oregon. Be at my door in a few days. Done and done. I see 1.50" diam x .250" wall DOM in my near future. Life is good. I now have a set of flat top Dana 30 knuckles for sale. What they fit, who knows? If anyone's interested, pm me, thanks!

That odd knuckle with the flat top is not from a Dana 30. All Dana 30 knuckles were round on the top.

Yeh their an odd looking pair of knuckles. Not totally d30, not fully d44. Somewhere in between. I suppose that makes them somewhat of a novelty item? Haha, oh well. I'm glad to be past this phase of the axle build.

I've been looking around about them odd knuckles. From what I can can find, they are from a drum brake Dana 44. Disc caliper mounts and dust shields won't fit on them.

Beat it to fit, paint it to match!
