t5 trans swap?

guys i really need some input on the whole speedo thing....i looked at justins pictures again on page 2 and his speedo output is friggin puny compared to the one i have...mine is much longer...and it seems that if i put a whole into the crossmember for the output to fit through it will hit the sleeve for one of the tranny mount bolts...are you guys using a different speedo adapter or something? im just using the one that came with my tranny (off the 90 mustang 5.0)...its starting to bother me now since i really dont want to have to redrill another mount bolt hole and then sleeve the crossmember and all...if worst comes to worst i aint running a speedo, which will be the 4th illegal thing on my street car (yikes!)
