I bought mine at a plumbing supply in Topeka.  Ask for an "8 inch, weld-on, pipe cap".  I cut it using a reciprocating saw with a heavy duty blade.  I built a jig because I'm lazy.  To cut drain notches (do this first), I filled a box with sand to hold the cap at an angle.

It took a long time to cut this way.  If I had to do it again, I'd use a cut-off wheel on a grinder.

so will this work for my yotas?   they have a larger diameter housing.

IIRC, I was thinking guys use them on toyota axles too.
The ID of the end of the cap is just under 8"....so you should be able to measure your axle housing to see if it will fit over it.

Here is a link to the specs (measurements) for them.

for the 8" cap.

The eight inch caps work great for the Toyota axle housings also.  I have done a few for Samurai owners, Toyota and also Sidekick/Tracker rears.  I have a jig set up for using a bandsaw, the plasma cutter is how I cut them now.   Don't forget to leave yourself a clean-out or drain hole.

man you guys rock !!!!

it would have taken several days to get this kind of quality info elsewhere.

thanks

now ive got another project to add to the list.

scott, id like one of those caps.  ill be up to deliver some yj springs to dave green sometime soon and i could get it then. would you like me to send you some $$$$$ in the meantime?


same price cut?
 

hey all....I was wondering if there are any others who are in need of a cap... so far scott and i have 6, 1 is for us, and i have 4 more on the way... i work in the field where these are very easy to get ahold of... we will more than likely take some to the melt with us too... let us know if you want them cut or un cut...

Thanks for all the info.
I did locate a few supply companies that sell the 8" diameter, schedule 40 (1/4" thick) pipe caps very reasonably.
I believe all of these places are located in/around the downtown area.

I'm using these on my rig with Toy axles.  I got them at last years Melt for $25 for the pair.  Work really well when bouncing off the rocks, they just fill up with mud easily.  Here's a couple of pics, sorry there not very good. (and no, my junk doesn't lean that badly, I was parking on a set of tires for the fun of it...lol)
