Transmission fitment question
I have a 84 corvette and I have the chance to purchase a 6 speed transmission from a 1990 corvette for cheap. Will this 6 speed transmission bot to my L83 350 in my 84 corvette? I can have a drive shaft made no problem. Guy has a complete 4+3 and complete 6 speed manual from c4 corvettes. I have a slow build project 84 corvette I want to swap my automatic to manual.

On this write up it refers to 86-88 years, will this be the same as my 84?

The Six speed may be Easier, Both will have their Challenges under the Dash & under car. But the Six your not Making a tub well to get and mount the Shifter in, instead your cutting a Well placed hole. Plus some other parts covered by the Previous Post.

I'm not going to bother to look these up, but:
Is the console top panel the same for a 4+3 as it is for the 89 6-speed?
Is the 6-speed shifter in exactly the same place as the body-mounted shifter?
Is the floor tunnel the same shape?
Is the C-Beam the same for the 6-Speed and 4+3?

Truthfully given today's Automatic Transmission, Other than personal choice there is no big advantage or Disadvantage between and in some cases auto's are a little better with no lost Acceleration while shifting.
But if you want a Manual car Buy a Manual car Making a Apple Into a Orange will always have it's Problems

Is this the drive shaft yoke that is needed for this transmission swap
http://www.parts123.com/parts123/yb....Z5Z5Z50000050F
Or If this one will work its a lot cheaper

*** Sonnax part# is for a T400 and other 32-spline but NOT the ZF
Do people use the T400 spline spec? Many likely have
There are less expensive alternatives.
I'd buy neither of those!

Do I need one with the offset gear reduction?
I keep thinking of things will my 700r4 transmission mount work on the 6 speed? The thread I am going by is converting a 4+3 to a 6 speed so I am unsure is the 700r4 trans mount will work on the 6 speed

Manual and automatic use different length C-Beam and driveshaft between transmission and rear axle. That is because of different rear axle. Your exising C-Beam should fit with manual transmission.

From googling pictures the stock 1984 starter probably does not clear the ZF bellousing. Not a big problem. Use another starter or modify the bellhousing.
#17
I am not going to use the 84 starter, I am going to buy a starter from a 1990 corvette same year the transmission I got but there is two starters to pick from a standard one and one that has offset gear reduction. Which one do I need?
#18
If you're looking to an "off the shelf" buy something that will reference these OE #'s 1998578 or 10455702 or 10455709. Any that have these same three #'s on them could maybe be considered OE.
Where are you located?
C-beam length is dictated by rear differential. D36 is one and D44 different.

I plan to get a off the self one, but again do I want a offset gear reduction or no? Or can you tell me what off set gear reduction is and does and why is it an option.

Stock 1984 starter has the motor in line with the drive gear.
With offset ger reduction you have the motor beside the drive gear and a reduction gear between them. This type uses a smaller lighter motor with more rpm. Typically all aftermerket ministarters are this type.
