I have found A 1989 f-250 with A EFI 302,5 spd transmision,and A manual shift transfercase will it all fit in A 91 ext cab 4wheel drive Ranger curently with A 4.0 5spd electric shift case?Will the hydrolic clutch hook up the same? Is there still room for the codensor in the front?Any help would be great.P.S. the reason I would go thru all this is I would love to put A snow plow on the Ranger for doing some store_n_locks with tight quarters I have A contract with,But I think it would drasticly reduce the life in the drive train. It already has 250,000 on the truck,but it still looks good.Please advise.

yes, it can be done, and you're very lucky to have the whole donor vehicle....
this 5.0 swap is done all the time, and has become a very common and reliable swap since there are so many aftermarket parts that cater to this swap.
Advanced Adapters makes a kit to do this swap....
James Duff has some advice too... http://www.jamesduff.com/broncoII/v8conversion.html
