I have been offered a diesel from a 1984 Mazda truck and two transmissions for $350 Canadian. I don't know the owner, and fear that the motor might be junk. Probably comes with the transmission you need.
Regina, Sask is in Western Canada. You can find out where by going here: http://www.expedia.com/pub/agent.dll?qscr=mmfn&&tpid=1&&&&dchg=&&zz=1048692854040&; EdB ----- Original Message ----- From: jgnat1488 To: biofuel@yahoogroups.com Sent: Wednesday, March 26, 2003 6:38 AM Subject: Re: [biofuel] Electric generators unfortunatly a gas chevette transmission will not work. It is an isuzu M75 (i think). Thanks for the offer. I feel stupid for asking bu where is Regina, Sask? --- bratt <[EMAIL PROTECTED]> wrote: > Do you need a standard Chevette transmission?
