P4529751 is a mopar p/n, sfi approved. Had one, but sold it. They are not that expensive, about $35 last I checked. Sorry I couldn't help you, I sold mine for 20 bucks I think and it was new.
 
# P4529751 Comes back to a flexplate... I just need the 727 converter cover...... mounts to the bellhousing just below the motor to tranny bolts....I will try to get a pic tomorrow.... Thanks

I may have one laying around. Will look for it. Pic might help me make sure I am looking for the right thing.
 
I don't run one on my 904........damn thing just made noise with the ARP converter bolts hitting it......if your car rearely sees rain there is no need for it.
 
Car will be occasionally driven on a dirt road. As my parents live on one. I think the actual name for the part I am looking for is small block TF727 dust cover.
Here is the yoke I won...

Still in need of a speedo gear for the 727. Lost the one in the a904 somehow. Have all the cables, just need the speedo pinion gear.. Anyone out there have an extra or know where to get one?

Moparparts.com and Manciniracing.com sells them. I have 2 if I can find them. Do you know how many teeth you need? That's real important or your speedometer will be off. I'm sure one I have was for a real high geared (like 2.76 gear) vehicle and the other for a low geared car (like 3.91 or something) so you see if you just throw anything in your speedo could be off as much as 30-40 mph.
 
Yeah, I have no idea how many teeth it had. I just need to obtain one so I know where to go from there as far as how many teeth. common sense tells me the more teeth, the lower the speedo will read. So once I have a known value as far as teeth vs speedo reading, I will know which way I need to go.

Please note: these numbers are for the standard style pinion gear
also last two numbers are the number of teeth, 2538945 = 45 teeth

triggerjay, here's a chart for you. You need rear gear ratio and rear tire height then just follow the chart for the correct speedo gear. I believe your local Chrysler dealer still stocks these tranny gears. Good luck.
 
Thanks guys.. I lost the thread, and just found it again! Good info!
