hope i can get some input . i bought a 67 beaumont conv (chevelle) a while back i have since taken the 396 engine and tranny out but when i looked at the tranny crossmember its boulted to the underside of the frame with a made up spacer about 1 inch thick . from all the info i have about the car it came with a 283 and powerglide the front end has been beefed up but i would think i need to change the crossmember any sights on the web or experieance would be helpfull i looked in the tranny area but dont see anything about this subject . thanks for any help.
