I am wanting to convert my 4 speed box to a 5 speed and have heard of kits that can be added to the 4 speed box. Are these reliable/as good? Where would I find one? Or is there a abetter solution?

You can find for example here: http://www.vizzamotorsport.de/

some body can explain how to do it ?
Thanks

ASK GUY.MAYBE HE HAVE FOR SALE

Greg Schmidt's tip's and tricks has nice explainations of these changes but i remember the 5 speed was a special item requiring an extra long case and modification to the body of the car for clearance. There do exsist short box five speed trannies but I have only seen one from an early Abarth.

Paul has both 5 and 6 speed boxes at www.scuderiatopolino.com.  $3200 and $3900 respectively.
