7.25 rear from 5x4” to 5x4.5” bolt pattern
I posted this in another thread but thought it might be easier for someone searching in the future to find in a thread specifically about this.
I recently swapped axles in a 7.25 rear from being 4” bolt pattern to 4.5” using axles and drums that I bought from Doctor Diff. The axles have the 4 bolt flange and slid right in. He also sold the 9” brake drums drilled for 4.5”. They have 1/2x20 wheel studs. I went with the 3” wheel stud option. As it turns out that is a bit overkill on length but the studs do hide under the dog dish hubcaps on my police wheels. The car is a 65 Valiant convertible slant 6 that originally had 9” drums all round. The front had the disk conversion done a while back and now the rear bolt pattern matches.
The hub diameter on the new axles is still setup for the small pattern wheels so hub rings might be worth looking into. Not sure if I am going to stick with the police wheels or go for an aftermarket wheel. The tires in the pictures are 215 60 15 and have plenty of room in the wheel well.
P.S. Some of you will notice that the brake setup is not 65 style. The rear is form a 73 duster that had 9” SBP brakes. Very similar brake setup but not exactly the same.
