is there a difference in crossmembers from 98-99?

im trying to finish this trans swap but ive run into a problem with the trans mount/crossmember. first of all i noticed that the trans that i pulled out was a tremec (3650?) and the replacement is a borg warner (t-45?). upon getting the borg warner in the car i see that the crossmember doesnt line up with the mounting points on the new transmission. i need to figure out whether or not the tremec (which i thought only came in 99-current), and the borg warner used different crossmembers...another thing i noticed is that the replacement mount i bought has 2 centered mounting bolts, while the one i took off the car had 2 offset mounting bolts (at the parts store i asked for the one for a 98).

my theory>> the car had a trans put in from a 99^ and therefore me switching it back to a pre-99 trans (t-45) means ill have to switch the crossmember back...(this theory only holds logic if there is indeed a difference btw the two crossmembers)!

look people maybe im not being clear on what i need/need to know. i have a 98 mustang gt with a 5spd tranny, the trans i pulled out was stamped tremec (i assume it was a 3650) and the trans i put back in is stamped borg-warner (i assume its a t-45) the trans bolts up perfectly, and is in the car but the trans mount location on the new trans casing is about 5 inches further back as opposed to the tremec one. what i need to know is were there two different style crossmembers used for each of these trannys, because the one i have will not work. i noticed that there are four holes in the frame where a possible crossmember could go and would line up perfectly with my mounting location, so this makes me believe there is another unit available, but i was hoping someone here could confirm this before i go to the dealer asking for a part that doesnt exist ya know?

this is a prime example why these forums should be better moderated...people can post all day about what wax they should use and other dumb **** like that, but as soon as i have an actual tech question i cant get an answer. maybe its just me but this site just isnt all its cracked up to be!

thanx for the replies guys, i ended up getting a mount fabbed up of solid steel. it looks really neat and has held up well, but im scared to get on it now cause i was told that solid steel allows for no deflection like the original rubber mount does so i could end up cracking the bellhousing or wearing out u-joints quicker due to hard launching. ive done a couple hard launches and power shifts, and it seems to be ok, but if something eventually does break i guess ill know why !
