Widening the front track on a MGB

For various reasons I would like to widen the front track on my MGB by two inches. I know it means new top and bottom wishbones but what I am unsure of is how it will affect the Akerman angles while turning on corners. I know Triumph used the same complete front suspension assembly on the Herald and Spitfire and the GT6? In this case the track remained the same but the wheelbase on the Herald was 91.3 inches and the Spitfire was 83 a difference of almost 9%
What I am thinking of doing in effect is similar, widening the track is similar to shortening the wheelbase. My thoughts are if Triumph got away with it why won't I
Can any of you enlightened enthusiasts tell me why it will or will not work and any remedial work I might need to do, one thought is that I may need to bend the steering arm away (?) from the wheel a little on each side.
I am also posting this question on MG Experiance

If you are only lengthening the A arms 1" the effect on Ackerman will not be noticeable. Lengthen the tie rods coming off the rack and you're in business. Bump steer isn't that great to start with and this shouldn't change that either.
