I have been researching and although it will cost a couple hundred dollars more to change the 67 skylark's 8.2" 10 bolt peg leg with the 12 bolt cover rear end to a posi, I rather doubt I can buy a true 12 bolt 8.5" rear end plus the new gears and bearings and stay cheaper. If I buy the bearing kit, posi carrier and ring and pinion and use my existing axles, how much is a reasonable cost to pay for having the work done to assemble this? I have a pretty good source on parts at wholesale cost, but wonder how much to budget for having it all put together. Yeah, it cost's nothing to do it myself, however time is money and I reckon I can spend my time making it elsewhere. Thanks guys. Jon
Assemble, including gear setup, no brakes - $150 at Moser Engineering. Good luck, keep us posted on what you decide and how it works out.
LOL... Moser is some 2000 miles away. remember to add the shipping cost in ...LOL You can not go by what a company charges you have to ship to. That is why you have local charges. The convenience of getting it done with out shipping. any where from 150 (easy rebearing to 250-300 for a full ring and pinion set up is a normal price. If you go to a high end performance shop you could end up with as much as 500-700 for a set-up. Be careful ask questions of your builder to determine whether they know there stuff in the area you are using them and see if they have references too. quoted ' I have been researching and although it will cost a couple hundred dollars more to change the 67 skylark's 8.2" 10 bolt peg leg with the 12 bolt cover rear end to a posi, I rather doubt I can buy a true 12 bolt 8.5" rear end plus the new gears and bearings and stay cheaper.

Dude, your fine...It is a forum... WE all are. Sorry if it came across critical. Not intended :TU: JIm J D

Hopfully this clears up the tech on these rears[/quote] I have the weird, 12 bolt cover rear end that I "thought" contained the 10 bolt 8.2" peg-leg gear insides. I believe it is the olds style, if that is 8.4, well, I only missed by 3/16" or so...ou: Upon re-reading my post, I messed up and the lesser cost was actually a 10 bolt posi unit, gears and bearings kit, and then about $200 more for whatever that set up is in my 67 skylark. So the parts cost, less shipping for a 10 bolt posi I was quote about $750 and then my actual rear end will be $850-900 depending on which spline count my axles have. That includes richmond 4:42 gears, posi carrier and bearing kit. I have a mechanic/hot rodder guy in his 50's that works at the shop next door and he has done many a rear end, so I was just wondering what the cost would likely be to hand him the parts and let him go at it. Sounds like it would be $900 parts and $350 labor for a total of $1250 complete, worst case and maybe $1000 lowball if he does me a favor and I have the least expensive spline axles. Now I can compare that to buying a completed rear end that is a posi and just swap that in and hope it works right. Thanks for your info Monzaz, you are a great help and resource.
I also have the 10 bolt 8.2. I raced it and did a 1/4 mile burnout. Myself I am going the route of new ring & pinion with a 355 ratio, new bearings & Eaton posi. The trick with this rear end is that it absolutely needs to be built right with the correct tolerances. I'm having mine build professionally. It's not cheap though.
