Re: Diff covers
I used the MiniSpares rod change version, and cut the detent lug off with a hacksaw

Re: Diff covers
Hi, I had the same problem after I found out that one of my covers had a split in it. I bought one of the 22G420 side covers and with a fret saw I cut off the "ear" for the detent on a rod change gearbox. With careful sanding and painting, you cant see the difference. R

Re: Diff covers
Just as another option here, some of the side covers for the Rubber Joints had extra meat cast in to them (quite like the same casting as S Plates) and can easily be turned in a lathe to take the S Bush and Seal. I haven't needed these in recent years, but in the 80's I did loads on them.

Re: Diff covers
That's what I have on 9748KO Chris ... 15 years on and never had a problem or leak !
That said, I'd have fitted 420's if I had them at the time

Re: Diff covers
I have turned many of the standard side plates and fitted the larger bush/seal...and as Andrew stated...no issues. Been doing this for years.Andrew1967 wrote: ↑Mon Apr 12, 2021 8:39 pm That's what I have on 9748KO Chris ... 15 years on and never had a problem or leak !

It is an inexpensive solution to the 420's ...............and there is an an abundant supply of the standard ones.
