Wouldn't a B body de wayy too wide?? B body axle housings are as wide as my wife's 1974 AMX.The 71-74 AMX is about 2 1/2-3" wider than Gremlin/68-70 Jav/AMX. I'm putting a 1969 road runner rear in my wife's 74 AMX. A Gremlin total drum to drum is right at 58 1/8 " or so!! B body is around 60-61".IFFF you can locate a 1957,58,59 ford passenger car. The 9" will bolt right in!! Don't even need to shorten the driveshaft..IF it was a 6 cylinder car already. thats what i have in my 1972. Fits great!! It is 58" drum to drum!!!! About 1/4 " narrower than my original 6 rearend. Also will fit right on the springs with NO pad moving! Just my 2 cents worth,Joe __________________________________________________ Do You Yahoo!?
