JMHO the holes need to be smaller the studs are 8 mm and stock pins are smaller the that.
The stock lock washer are the same size as the cone washer.
Again just JMO the the lock washer is going to try to fall in the hole.
We will be heading out the 50 as well, it's longer but the wife is tired of the 15 and that part of the desert. We will be leaving Morro Bay Saturday and plan on arriving on Monday also. We will be towing and move slower, Look for us along the way.
The Gaskets and not made with precision, I usually have to push them on especially the fronts.
If you have a rear gasket I would mimic that.
I have rear gaskets here form two different manufacturers and there not exactly the same.
To be honest I wasn't happy about it and did not know until I went to install then. if they would have just left the pins the same size as stock the the individual could decide whether or not to add the extra pins and holes. 🤷♂️
Unfortunately a stock front flange won't fit the rear if the rear hub has been modified to run RCV rear shafts. 🤷♂️
I like the idea of having one lightweight cap that would work for all !! ;)
The other option is the carry a spare RCV drive flange.
Yes, just with out the extra holes and they mimic the front drive flange.
I think the cap should look just like a rear flange and gasket and it would work on the front or back and with all axles if it has the hole pattern like the rear gasket.
It's as simple as turning the the hole pattern...
There basically the same just four more holes symmetrical to the stock two dowel pin holes and 8mm.
The same cap could work for all applications as the the dowel pins are not necessary for a cap purpose
I think the idea is to have the center filled 🤷♂️
If your going to make them maybe you could make them with 6 dowel pin holes for us guys that are running RCVs and the dowels pins are 8 mm with RCVs
YES you can run a front flange on the rear full float axle.
Unless it been modified to run RCVs.
And why I wanted that spare RCV flange from you Steve!!!
