Flange Plate Steering Relay to Chassis 217694

I managed to salvage from my old chassis the plate that goes on the underside of the chassis that braces the steering relay.
When i came to attach it to the new (Richard's) chassis, i have found the holes are in the wrong / different place.
I have a choice of either buying a new one (a plate, not a chassis), for about £25 which i presume will fit my chassis & relay, or I drill some holes in the right place in my plate.
Whilst I know that steering is important (!), i am thinking the plate would still be plenty strong enough.
Any advice?

I made a new one as I wanted something with a bit of beef to it. It helped that I had a a bit of tube about the right size. The new replacements didn't look strong enough to brace anything https://www.landyzone.co.uk/land-rover/steves-unexpected-series-3-rebuild.292955/page-28

Large forces pass through that flange. You need to re-drill holes anyway, so increase material thickness to around
6 mm and ensure it fits tightly around the relay. Loose all the movement if you can.
