Finally got my new 5th gears for the Transmission . I have the early 6.34 transmission which has a different ratio on the 5th gear. Dont mix and match these gears the pitch is different. Swap them as a set.

5th gear shifter fork is also something to watch out for. My old fork is cracked straight down both dowel pin holes. The dowel pins have a taper to them so that they will only go in and out one way. They are also stronger than the cheap dowel pins from the hardware store. It looks like they are 2-3 wall thickness. So it looks like some dingle berry PO drove my dowel pins straight thru the shifter fork cracking it on both pin holes. In compairing my old fork and the new fork, the old fork is heavier and has rounded edges. The new fork is lighter with sharp flat edges and rough cut machine work on the machined surfaces.

New 5th gears installed, waiting on paycheck still to shim the main shaft to be able to finish Transmission rebuild, new 5th shifter fork installed permanent.

I want to have the option of running a later model NV4500 if necessary later down the road so my plan was to get the NV4500 bell housing from Advance Adapters and drill my case to match since there is enough room on the front face of the Transmission for both bolt patterns. I was staring at the front input the other day and realized that the early trans like mine takes a different input bearing, cup and bearing retainer than the later models. 5.125 vs 5.6 inches. I also realized that boring the case out was not going to be an option due to the bolt pattern on the retainer. So that leads me to the machine shop to fab up a spacer ring to make up the difference between the two. Something else to be aware of

Having access to a lathe is awesome, I have my new input retainer on the way and my spacer ring is complete, This will allow me to run the later 5.6 pilot bell housing with my early low gear 5.125 input

My last parts to finish the build on my Transmission is here, this is the adapter ring I spun up to adapt the early bearing retainer to the later bell housing

I got the correct concave washer and nut to go with my 23 spline output shaft, the 3 peice washer does not fit unless it specically says it fits 23 spline shafts. Make sure you get the concave washer, that provides extra tension to keep the nut from backing off, 270 foot pounds is alot and its really hard to hold the Transmission steady

I am still going to re torque the 5th gear nut when I get some help and then seal the rear adapter housing and top cover up but here is what it looks like done. The 29 spline shafts have a bigger nut and take even more torque than the 23 spline I have
