What are you planning on using for a brake rotor?

Not quite sure yet. I like the idea of something like this http://www.tmrcustoms.com/store/inde...1efdf9d2699198

but the 3/4 ton Chevy rotors, I dont think, will allow the LR lug pattern.

More pic's tonight....

I was tossed up on the thought of a drill jig though. I will measure the original D50 hub/wheel pilot tonight. This way a guy could fill the two holes, grind the fill plug to "close enough", drill the new LR lug holes, then face in the lathe while turning the pilot.

Im picking up several pipe plugs today to fill my overlapping holes. Ill post pics
That sounds a good plan, works well for anyone that doesn't have a lathe at home & needs to send the hub out for machining.

What size pipe plugs were you using ?

Tapped one of the holes tonight. Went with 3/8 pipe from the back side. I figure the plug is there to fill the overlap so the knurl on the stud will hold. It doesn't much matter to me that the plug doesn't fill the hole completely. These POS Home Gestapo plugs don't have a flat end. The ones from McMaster do....

I think I will use the 3/4 ton Chevy rotors because I have 4 of them and 4 hubs to match. I will probably need to plunge an end mill in to "spot face" the new LR lug holes. The original D50 rotors are a bit deeper than the 3/4 chevy....

Anyway, POGTFO.....

Looking at pic's of the D50/60 brake discs, the after market ones appear to not have the slots & casting humps on the back... might be worth using new discs, would save some machining time and that'd offset the cost of them if outsourcing the work.

Been doing lots of reading on all the different options on building 609 axles and as getting used stuff here is a royal PITA, so thinking of just building out off aftermarket stuff. By the time I've driven round collecting old rust bits or stripping stuff off trucks in the junk yard that's 3hrs away from home.... these look so much better option to mount onto a Ruffstuff 9" housing :

At that point you might as well buy their hubs as well, machined to 5x6.5. $400 for the pair is not bad at all.

Was looking at all their parts.... guess I need to start dropping hints to the wife about needing new axles

If you contact them about the hubs, please let us know what they say about having a set of their 8x6.5 "blanks" drilled for 5x6.5

I emailed them. I think the inside guy was a bit dense as he replied that the 5 and 6 lug hubs were not a large enough diameter for the 5x6.5 pattern....

I think the new parts are the way to go. The brake rotor thing is a big issue. Dodge 2nd gen 1500 front rotors will work, but must be bored and redrilled.

Im doing this because I have the hubs/rotors/brakes/ect. I like the wolf wheels. I want a bit wider stance. Im tossed up though. Toy diffs and 30 spline alloy is all I need strength wise. But I have all the parts to fully Dana 60/arb/35spline swap my junk.

I may keep my rear Sals... and swap the spindles to the D50/junk then build the 60 front I have to match the width. Its just WAY overkill for "not a crawler"

Best of luck in what every you do!!

Good to know about the Dodge rotors - I assume this means 94-01 dodge ram 4x4 1500 front rotors?

Looks like the Chevy rotors & single piston calipers are the only ones that'll work with 15" rims, the Dodge ones look to be all over 12" diameter.

Most of the dodge ones I have found are about 11.5", but I can't find anything that has a large enough hat diameter to comfortably fit the 6.5" bolt circle. Spent about 45 mins on RockAuto last night looking at photos and drawings.

I'm confused here.... You guys need 1 ton hubs, designed for 8 on 6.5"..... These don't fit 15" rims, do they?

Sort of if you use the Chevy 3/4T disc's and single pot calipers. Depending upon the rim backspacing you may need to grind the caliper for clearance. From what I've read so far with about 2.5" or less you don't need to grind... over that depends upon the rim.

But the down side to that is a crappy scrub radius... Not too much of an issue as long as the tires arn't too large.

Ok... here's a really dumb question..... why not just use D90/110 vented front rotors. There being reverse fitted with the hat towards the hub, have the right PCD and a 101mm bore... would they fit ?

Looking on Rockauto, there all listed at 298mm (11.73") diameter so similar to the Chevy ones. Would work with the Chevy caliper and be good for 15" rims too

https://www.rockauto.com/catalog/mor...768&cc=3111073

If not mounted to the rear of the hub, just front mount straight onto the studs... might need to turn the hub OD a bit... ? Would move the caliper outwards a but that only needs a spacer for the mounting bracket then. On a rear fully floating axle just weld the bracket on where it lands.

BTW... Found a note on one Chevy forum that the 12.8" 1977 K20 front rotors will fit 15" rims using the Chevy calipers... just need to watch the BS.

200 series Land Cruiser front rotors may work for re-drilling, but they would not fit a 15" rim:


7.64" diameter rotor hat, but 13.4" diameter rotor.

Thinking.... if the hub doesn't have enough meat on the back side to get down to 101mm, could it be turned to 101mm on the front, if not the disc would need to be opened up a bit. Either way, quicker than having to re-drill the holes in a disc... so should be a bit cheaper too.


If it all can be accommodated on the hub.... winner... keeps the service parts all off the shelf

The 90/110 rotor hat is tiny... no way you could fit it over the front side of the hub (slip on style)

Maybe you could make it fit the back side of the hub...

I am on to 05+ Ford Super Duty front axle parts now after reading about them all night... not sure of the viability of converting to 5x6.5 though (the unit bearing is huge)

I did say the hub would need machining.... As long as there is still meat for the studs its OD can be reduced plenty.
