Except.....steering wheels are not only subject to steering (rotational) loads.
There can be a lot more going on! Situations which can be combining the shear loads with other loads.
I suspect things will be different if you are using period-correct tire profiles on The D Replica vs big rubber on a Daytona coupe.
But the XK engine and automatic transmission will be a lot of weight over the front wheels.
It will never be as easy to install steering assist as it was...
It seems odd that Fran would produce an oil filter adapter for this small community of RCR D Type replica purchasers, but never have offered to any I know of. Not being omniscient (yet) anyone...... please enlighten me!
With the slope of the engine mounts, any significant shift side to side effectively raises the engine relative to the chassis. Can you measure and photo height of the engine vs the chassis and clearance cam boxes to cowl?
To the Jag experts, is there a lower profile oil pan for the XK engine?
