i need to know the size of a screw. it goes behind the gear box on a universal joint. the screw holds the universal joint to the driver shaft for the front tires to work. right now i have rear wheel drive. does anyone know that im talking about?

I think its a m3*3 grub screw(set screw).If its where I think you are talking about.

i did a quick fix. i found a small screw laying around so i used it. so far its holding.

how big are the m3*3 grub screws? i'd post a pic of where the screw needs to go but i dont know how.

yep I think it is also a 3mm grub screw from memory. Should be able to source that at your LHS.

Cheers
