Alfonso,
I debated RH or LH but, decided on LH as I use my fun cars on the road putting on 3-4K miles/yr in 300 mile trips /outing ...Was concerned especally with passing situations (passing trucks in a LH country with RH drive)..So settled on my SPF MK11 (clone of 1015 Miles/Hulme car..exact but, without the red front fender tops and meatballs static cling not painted) with LH drive and center rod shift (I didn;'t want cable but, that's personal desire and not needed) and a 427FE block like original.
All replicas are clones (not original) so all have some compromises and we each arrive at our own compromise threashold (my car represents my threashold)...Was also considering a T44 transaxle but, where I use the car for more pleasure than race here again compromised for roadability.
See my car pics in Superformance Forum under "P2125 on the road ect"
Regards, Steve
ps...let us know what you decide but, I would recommend you talk with Olthoff Racing for your needs.
