The bottom tube of my 6/70 240Z Macpherson strut has a horizontal plate inside about 3/4â€ from the bottom opening. Recently purchased new ball joints with larger diameter stud and used later-model steering knuckles fit together well. My problem is that the new stud is about 1/4â€ longer than the original stud and won't fit inside the strut, interfering with the strut plate. I havenâ€™t cut down the stud of the new ball joint yet because I feared it would be of hardened steel (difficult to cut) and the hole for the cotter pin/castellated nut would fall right in the middle of the cut. Alternatively, I wasnâ€™t sure if drilling a whole through the strut plate would affect the structural integrity of the strut. Has anyone seen this problem and have a fix thatâ€™s worked?
For a stock 1970 240Z, what is the maximum rim width (assuming 0â€ back-spacing) that will fit inside the rear wheel wells without rubbing on the fenders? Iâ€™d like to install 225x60x14â€ (or 205x60x15â€) tires on 5-slotted, dished, brushed aluminum rims (maintaining the original overall wheel diameter of 24.7â€ based on the stock 195x70x14â€ wheels). Iâ€™m not sure what the width of the stock rims is (5â€ to 7â€?) or what rim width to purchase for the new tires that wonâ€™t require trimming the fenders. I have located used 5-slotted rims in 7 1/2", and 8â€ widths (canâ€™t find them in 5â€ to 7â€), but have been told that the wider ones will rub on the fenders. Does anyone have any hands-on experience with this situation on a stock 1970 240Z?
