Does anyone know what radiator would be correct if the Build Sheet shows BR in box 46 on a 1970 Chevelle SS built in Kansas?

Thanks

what about a PD radiator?
For 1970,the standard Radiator for those three applications was the 3 row radiator,as well as the L-78 engined Chevelle.Transmission type did not dictate it.
When Air Conditioning was ordered on the L-34,or a 4:10 Rearend was equipped on the LS-5,LS-6,then they would receive the 4 row HD radiator automatically.But when the L-78 came equipped with a 4:10 rearend,it still was built with the Std. 3 row radiator.

1970 Chevelle STANDARD radiator suffix tag codes:
*L-34 Manual-BE
*L-34 TH400-BK
*L-78 Manual-BO
*L-78 TH400-BJ
*LS-5 & LS-6 Manual-BQ
*LS-5 & LS-6 TH400-BR

1970 Chevelle A/C & HEAVY DUTY Radiator Suffix Codes:
*L-34, L-78 & LS-5, LS-6 Manual-PA
*L-34, L-78 & LS-5, LS-6 TH400-PD
