Gary,
Firstly, sorry the Sprint needs more work than originally thought.....................I honestly dodn't know.
Secondly, as other's have said they are YOUR cars and you do as you wish..........
Thirdly, before you go down this route, remember me telling you about the "mint" Dolomite Sprint shell that as resided in a garage near me for years, plus a 1980 White Sprint (not so mint) that sits outside and along side the garage?.................
I can try and find out if the owner "would sell" but I have been trying to see somebody at the premises for years BUT I did see somebody there last weekend and he said he would mention it to the owner...........
So you want me to enquire?.
