RCG-400 Transmission Crossmember 84-88 G-Body Cars

RCG-400 TH400 transmission crossmember fit perfectly without an extension in my 1986 Oldsmobile Cutlass Supreme RWD. I was told year's 1978- 1984 would need an extension and they were right i didn't need one because the driverside of the g body frame on my 1986 has the front mounting area and then behind it about another foot is another rectangular mount with the teo holes in the bottom to access the nut and bolt with a long socket. If you need to know for sure if this RCG400 TH400 transmission crossmember will fit in anything g body past the year of 1984 without the extension. Also come super early on delivery
