inspection plate gearbox

hi
just changed my oil on my 99 td5 auto and when i was doing the drain plug up i noticed a round inspection plate missing on the bottom of the bell housing about 4 inches from the drain plug,any one any idea of a part number for this or do you think i could make one.
thanks for your help

FRC7706 cover
FRC7707 gasket
SH106151L M6x15 screws x3

The numbers may have changed now but just Google them

If it's the 4" hole on the plastic underside protection, then it's no point to it really. Mine has not got one either & never caused any problems.

I'm not 100% sure but I think this might be the hole on the bellhousing that gives access (on an autobox car) to the Torque Converter (TC) flex plate bolts.

If it is, there should be something to caver the hole otherwise road crap will be able to access the TC

thanks guys
it sounds like that frc7706 plate just googled it but cant find a picture of it but it sounds like the one im missing.thanks for those screw sizes just in case i cant get one quick to spain ill try and make one.
cheers guys
