Don't think the footprint is relevant Peter. My '76 was near rectangular, not the very trapezoid shape of later cars and I didn't have a problem with the inside of the screen, nor with the '93 which is 1" wider at the rear than the '76...
Of course, both are much narrower overall than the new generation +8 smile
