gearbox bolts

Hi im trying to source the 2 small bolts which tighten onto the side of the gearbox on the bottom, im not sure what the part is called but they squeeze the end housing and gasket tight to the side of gearbox..  :dontknow: the reason i need them bolts is i leak gearbox oil through that part, which is the lowest point of the gearbox when you look under the car. the bolts in at the moment seem to tighten to a certain point then go loose.

Any help is much appreciated to get those bolts! I know the description is tricky to understand so i can put up pictures of the part i mean if needed.

Thanks

gearbox casing bolts, housing bolts not sure. id call them casing bolts! do they sit directly under the diff?
if its leaking its probably the gasket itself or bodge it over with some sealent, someone may say different!

yes casing bolts!!   thankyou, i couldn't think what it was called. hmm well its just i dont think the bolts are squashing the gasket enough, its like they are the wrong bolts. I cud possibly try and seal the gap somehow but im not sure what would be best to use?

is it a cork gasket do you know? i cant remember what they are. i ask because a cork gasket will leak if if to tight.
take the bolts out and check the threads see what there like
id go main dealer or nip to a scrap yard and take a load

not too sure what the gasket is, ill have a look, yeh thats a good idea. thanks.
