VS57 Mounting Brackets

This table lists VS57 mounting brackets that were available up until the end of 1956. Many of the 1956 brackets are also applicable to the 1957 model year, depending upon the engine options for that year. Some of these brackets require reinforcing braces which I will list separately at a later date. This section is by no means exhaustive so please contact me if you have any amendments or additions.

NOTE:- As I'm finding out about more brackets a trend is emerging that indicates that at least two versions of the brackets were made. The first version was generally stamped steel or cast iron, and the second is cast aluminum. Why McCulloch made two versions is not clearly obvious however I suspect that their was a change to the use of the aluminum mainly due to lightness and strength, although the additional cost also implies that this extra strength was needed. It's possible that when McCulloch switched from the 45 lb springs to the 65 lb springs bracket flex was occurring - hence the need for stronger brackets.

BUICK

 

AB-1000 B 1954 to 1956 Buick

CHEVROLET

   

ACH-1000 B or CH101  - 1955 to 1957 Chevrolet. CH101 is the cast iron version and it also bolts onto the inline 6. I'm not sure if the aluminium ACH-1000B bracket has the same flexability or not.

 

ACO-1000 or ACO-1000 B 1955 to 1957 Corvette

This is the mounting bracket used to mount a Paxton supercharger on a Corvair engine. Lettering cast on the side of this aluminum bracket states "CORVAIR" and "PAXTON PRODUCTS,SANTA MONICA,CALIF" as well as the part number 38539-A. The second part of the bracket carries the part number 38681.

1963-64 GT hawk and Lark. These were designed for the later SN units so I don't know how well they would work with a VS unit. Part numbers were 1557957 for the bracket, 1558664 for the idler arm and 1558663 for the idler pulley.
