more opinions please - narrow buggy spring

I am in the process of updating the drivetrain in my 1931 Model A coupe. I have a rear-end from a 1993 S10 Blazer 2x4 ready for the swap. The original rear perches are 49 1/4 inches apart. I will not have that much space with the S10 rear (maybe 44 to 45 inches).

Can I, should I, have the original buggy spring narrowed?
Can I use a spring from another year to fit and achieve the correct ride hight?
Does some one sell a narrowed buggy spring for this application?

Thank you for the responses earlier today. I just do not want to fix a $100 problem with a $300 solution.

I am leaning toward using a swap meet spring from another year.
Does anyone know which year might work?

All suggestions are welcome.
Thank you.

There should be several spring shops in the DFW area that can shorten the main leaf and roll new eyes on it.
I would talk to one or more of them and see if they want the perches mounted on the axle first to ensure a perfect fit.

Check with these

Speedway catalog has spec for spring and perch position. no cost. find a spring shop - trailer - repair - black smith. A friend of mine had same problem with his A main leaf . he tryed eaton. did not work out.

 

I had the same problem, wanted to run the buggy spring only narrower. Well, it didn't work out after having a new main leaf made and it not being done well ended up with coilovers. Not telling you what to do but for me it was a waste of money.
Where is Keller? You can have a look at this one if you want.

 

thank you for the posts. I fixed the problem by buying a 1968 8 inch rear end at the dfw swap meet today. Anyone want to buy a very nice S10 rear end???
