Hot Rods Model A (new rear crossmember) ?

Was hoping to find some pics or details about installing this new crossmember onto my original Model A frame . Im replacing the front crossmember as well along with the tranny mount . But thats down the road so im just concerned about the rear crossmember for now .

Do i cut any length off the original frame ?

I do have frame dimensions , but just cant find any builds reguarding this crossmember and where it should be located .
Crossmember is from speedway , part # 910-82831

Going to be using a 9" ford , Deluxe coil over kit , 32" radius rods with panhard bar kit from speedway #916-49060


Thanks for any help and or pics with dimensions that you have done .

 

From the catalog page: This piece is designed to work with "pinched" aftermarket frames, but can easily be made to work with original 28-31 frames with slight modification.
Are the ears intended to take the top of the coils?
You might call them, and ask for some installed pics.

 

Going to call Speedway today , not sure what the ears are for . So has anyone hear done the same crossmember on a stock 28-31 frame ?????? Any pics ?

Thanks

 

The two tabs on the left and right are for the rear body mount bolts.

 

Old thread here, but I have the same question on installation of this speedway rear crossmember. Any wisdom from the mount?
