Are there any websites or dealers that sell a complete conversion. The only one i have found so far is www.bieberfever.com, but they ask for a ton of money, around 1500 dollars for a used t-5. Piecing together a conversion isnt my thing so im trying to go this route. Thanks.
I think some of the places that sell on used parts on eBay might have a kit. That route is more expensive though. If you want to get everything at once, you may be better off going to a local junkyard where they know a little about Mustangs and see if they have everything. The cost cost effective way is to piece it together though. It all depends on convenience vs. price and what is best for you.
Your best bet is a salvage yard. That is exactly how I got my car swapped. You need, the trans, bell, clutch, PP T/O bearing, cable, pedals, harness from left kick panel to the transmission, driveshaft, possibly a crossmember, my auto one was the same. you might need the computer, but others have swapped it with out it.
