i have the 3.73 set for the 12-Bolt in the picture I showed! Those were special made! That is going in my hot car! I have a 6 speed going back in that car!

I did not not have a new Ring & Pinion for the newer just bought Tom's 10 bolt, so I bought a 3.73 on Monday. Tom' wife (bless her heart) is struggling to get everyone stuff they need, so I didn't want to cause her to lose time on me and my order! I am used to noisy, as I have a Rock crusher in one car, a gear drive in another car and headers on two of the four cars!

i assume the extra attention to the gear cut is strength and noise reduction!

Thanks

Yes that is the part number!

The Richmond I bought was one of their special HD units! The 2nd thru 5th mimic a Muncie close ratio box! The Richmond’s that I selected for 2-5 are 2.22, 1.57, 1.24, 1.00). This I essentially have an M21/M22 in the car. For the 6th gear I selected a high torque capable (not really an overdrive unit) of .80. That is a unit designated as Special Heavy Duty 9 DP Road Race Gear Sets (this Gear also is far stronger, but the disclaimer says will produce more Gear noise than the standard gear sets! They also have one other HD gear for 6th in .84. If you select one of these gears, they stamp the case HD! The standard 6th gears are .52, .55, .59, .62, .76, .81, .86, and .91. On my first since I am sticking to 10 inch rims to be whatever class legal, if I ever decide to come out of my private Road Racing Canyon to play with the Corvette big boys, is a 3.04, as the car can totally roast off any tires in first gear! I love the Long Mfg. shifter set up! That thing alone with Heim links now runs about $700 or more and is a work of art! I did buy a short shifter to mimic the C2 config. I don’t know how I stack up against what I perceive is the aftermarket favorite Tremecs and Keisler units.
And ps- I haven’t done anything but cut the basic size of it, and I want to gold plate it just for the hell of it, but I was going to mill a Ferrari style shifter gate, that I can install to lock out 1st and 6th, so the fellow racers can’t whine and cry!

I will let you know what I get! I had it shipped to my Brother, who can see with his Security whether A fly landed on his porch! I will have to do the Brother bonding thing (and listen to Porsche talk for hours), when I go pick it up!

Cool I picked my Tom's Differential Corvette Ring and Pinion up from my brother last night and he is at the moment into the Gun collection, getting optics, picatinny rail quick disconnects, etc., but Porsche talk did happen as we are going to:

The cool LAX Airport Hilton Memorabilia, Clean parts, and Literature indoor convention room Porsche mostly and some VW tables full of stuff swap on March 1st! Let see over the years have seen Leno, Seinfeld, Garreston, Redman, Elford, P. Hill, and a slew of others there! Fun talking to such guys as I paw racing stuff! The following day is the Anaheim Phoenix Club Porsche outdoor dirty parts and indoor vendor swap meet and the grounds are full of enthusiast cars! We have taken our 300+ hp IMSA leveled engined 1967 911S, and our 1978 911 Turbo, with the 934 unit and mega boost to the 2012 &2013 shows! My brother is stalled on his full race 1973 Porsche RSR build and we have made progress on the 1969 Beach Racing MK-5C Formula 2 Car with Porsche Flat-6 2.4 liter engine that no one knows about yet, that we hope to unveil at the following years show. Need to talk to the Porsche Performance Center in Carson, CA across from the Goodyear Blimp as to using their track to get the bugs out of the Formula car and see if they want to participate in showing it next year. The Friday and Saturday many many of the Porsche shops open there doors for visitors, and some feed you! Then in April, it is the big Luftgekuhlt show, location undetermined at the moment! The displays were unbelievable with like the 1973 Can Am Penske/Donohue 917/30 and many factory racers and famous cars on display and well as enthusiast cars by the gzillion while you drink German beer! Therefore while picking up this fancy Corvette gear set I showed, I did not escape without Porsche talk!

PS SoCal car culture is still alive and kicking! I kind of would like some Corvette people to go see these, because these events are an example of what us Corvette guys should be doing Annually!

Thanks for coming on and updating us! Other than the four Corvettes in the family I have tried to supply with your parts, I didn't quite get to my Muscle cars! Next project I have nearing completion is a 1965 Elco, that I was thinking of changing to a Dana 60!

You guys did great for all of my Corvette Diff dreams! We have two 12 bolt setups and one BOE 10 bolt and one 10 Bolt getting a super-10 build using your parts!
