Re: [Chrysler300] Spindles, brake conversions

[John Hertog <crossram@xxxx>]

Hi Doug, and Roger at AAJ...

I do believe I can help somewhat. Let's forget about 55-56 Chryslers for now and work on '57 thru '65. I don't know enough about the C300's and 300B's . Their front end is in a group all by itself. 

Going backwards, the '65 300 and 300L ( and later drum-equipped 300's) are the easiest to convert to disc brakes. No need for a kit. Just find a 70-71-72-73 Chrysler with front discs, pull the spindles and lower ball joints off together with the master cylinder, both brake lines down to the proportioning valve, and the valve itself. It's a bolt-on no-brainer . No need for a conversion kit for these cars, there's plenty of donor cars in junkyards that fit the bill. 

1963 and 1964 use part number 2207031 spindle. The bolt pattern where backing plate and steering arm attaches to spindle is different from previous years. I don't think AAJ or anyone else makes a disc conversion for that particular spindle. The mounting bracket for the caliper would have to be different, due to different bolt pattern.

BUT - if you own a 63-64 Chrysler and want to use AAJ's kit, then all you have to do is replace the spindle and steering arm on your 63-64 Chrysler, using short wheelbase components from earlier years. 

1957 thru 1962 Chryslers use TWO different versions of the SAME spindle. Therefore AAJ's kit should work equally well on either of the two, since the bolt pattern for backing plate / steering arm is the same. AAJ's bracket will mount to both. 

What's the difference between the two versions ? Ball joint size... the top and bottom holes in the spindles that the ball joint stud goes into is larger on LONG WHEELBASE cars . 

Long wheelbase cars use spindle #1670320. Short wheelbase cars use # 1671362 . Again, both of these spindles have the IDENTICAL 4-bolt pattern where the backing plate and steering arms attach. Therefore I'm pretty damn sure that Roger Thomason's disc conversion kit fits ANY Chrysler 1957 thru 1962. Period. 

Now - if you own a '63 or '64 Chrysler and wish to use AAJ's disc conversion kit, you'll have to procure a pair of 1671362 spindles (and matching steering arms) from an earlier Chrysler short wheelbase car. Replace those, then install AAJ's kit, and you're all done. 

What's a short wheelbase and a long wheelbase ? Oh, that gets complicated. 

LONG WHEELBASE (126") 
all 1957 Chrysler cars : Windsor C75-1, Saratoga C75-2, NewYorker C76 and 300. 
1958 Chrysler: Saratoga LC2-M and NewYorker LC3-H and 300D, (except Windsor ) 
1959 Chrysler: Saratoga MC2-M and NewYorker MC3-H and 300E,(except Windsor ) 
1960 Chrysler: Saratoga PC2-M and NewYorker PC3-H and 300F, (except Windsor) 
1961 Chrysler : New Yorker RC3-H and 300G RC4-P
1962 Chrysler : New Yorker SC3-H


SHORT WHEELBASE (122")
1958 Chrysler Windsor LC1-L
1959 Chrysler Windsor MC1-L
1960 Chrysler Windsor PC1-L
1961 Chrysler: Newport RC1-L and Windsor RC2-M
1962 Chrysler: Newport SC1-L and 300 SC2-M and 300H SC3-H
1963 and 1964 Chrysler : all models

Hope this helps...
